Me. Justice Marshall
delivered the opinion of the Court.
This case presents the question whether provisions of the collective-bargaining agreement between the International Longshoremen’s Association (ILA) and employer organizations in the shipping industry which were adopted in response to the technological innovation of containerized shipping are a lawful work preservation agreement. The National Labor Relations Board held that the provisions did not preserve traditional work opportunities for employees represented by the union, but sought instead to acquire work they had not previously performed; therefore, it concluded that the provisions violated § 8 (e) of the National Labor Relations Act, 29 U. S. C. § 158 (e), and union action to enforce them violated § 8 (b)(4)(B) of the Act, 29 U. S. C. § 158 (b)(4)(B). International Longshoremen’s Assn. (Dolphin Forwarding, Inc.), 236 N. L. R. B. 525 (1978); International Longshoremen’s Assn. (Associated Transport, Inc.), 231 N. L. R. B. 351 (1977). A divided panel of the United States Court of Appeals for the District of Columbia Circuit declined to enforce the Board’s orders. 198 U. S. App. D. C. 157, 613 F. 2d 890 (1979). We granted certiorari, 444 U. S. 1042 (1980), to resolve a conflict among the Circuits on this important question of federal labor law.
I
This controversy arises out of the collective-bargaining response of the ILA and the east coast shipping industry to containerization, a technological innovation which has had such a profound effect on that industry that it has frequently been termed “the container revolution.” In the words of one observer, “containerization may be said to constitute the single most important innovation in ocean transport since, the steamship displaced the schooner.”
A
Containers are large, reusable metal receptacles, ranging in length from 20 to 40 feet and capable of carrying upwards of 30,000 pounds of freight, which can be moved on and off an ocean vessel unopened. Container ships are specially designed and constructed to carry the containers, which are affixed to the hold. A container can also be attached to a truck chassis and transported intact to and from the pier like a conventional trailer.
The use of containers is substantially more economical than traditional methods of handling ocean-borne cargo. Because cargo does not have to be handled and repacked as it moves from the warehouse by truck to the dock, into the vessel, then from the vessel to the dock and by truck or rail to its destination, the costs of handling are significantly reduced. Expenses of separate export packaging, storage, losses from pilferage and breakage, and costs of insurance and processing cargo documents may also be decreased. Perhaps most significantly, a container ship can be loaded or unloaded in a fraction of the time required for a conventional ship. As a result, the unprofitable in-port time of each ship is reduced, and a smaller number of ships are needed to carry a given volume of cargo.
Before the introduction of container ships, and as is still the case with conventional vessels, trucks delivered loose, or break-bulk, cargo to the head of the pier. The cargo was then transferred piece by piece from the truck’s tailgate to the ship by longshoremen employed by steamship or ste-vedoring companies. The longshoremen checked the cargo, sorted it, placed it on pallets and moved it by forklift to the side of the ship, and lifted it by means of a sling or hook into the ship’s hold. The process was reversed for cargo taken off incoming ships. With the advent of containers, the amount of on-pier work involved in cargo handling has been drastically reduced, since the cargo need not be loaded and unloaded piece by piece. The amount of work available for longshoremen has been further reduced by the shipping companies’ practice of making their containers available to shippers and consolidators for loading and unloading away from the pier.
Containerization, then, was a technological advance of great importance to the shipping industry which at the same time threatened the jobs of longshoremen by dramatically increasing their productivity. As one might expect, the subject has been a hotly disputed topic of collective bargaining between the union and the employers. We are concerned with the results of that collective-bargaining process as it affects the shipping industry in the Ports of New York, Baltimore, and Hampton Roads, 'Va.
B
It is necessary, in discussing the collective-bargaining agreements here at issue, to define certain industry terms of art pertaining to containerized cargo. Loading cargo into a container is called “stuffing”; unloading cargo from a container is called “stripping.” Containers holding goods beneficially-owned by one shipper or consignee are called full shippers’ loads (FSL). Containers holding goods belonging to more than one shipper or consignee are called consolidated container loads. Such cargo is also called “less than trailer load” (LTL) or “less than container load” (LCL) cargo.
The first collective-bargaining agreement to contain a provision dealing with containerized shipping was the 1959 agreement between ILA and the New York Shipping Association (NYSA). At that time, containerization was in its infancy. The provision in the 1959 agreement was prompted by a dispute over the use of Dravo containers, boxes eight cubic feet in size. See International Longshoremen’s Assn. (Consolidated Express, Inc.), 221 N. L. R. B. 956, 957 (1975), enf’d, 537 F. 2d 706 (CA2 1976), cert. denied, 429 U. S. 1041 (1977). The agreement recognized the right of NYSA members “to use any and all type [sic] of containers without restriction or stripping by the union.” 221 N. L. R. B., at 957. In return, NYSA agreed to contribute royalty payments on “containers which are loaded or unloaded away from the pier by non-ILA labor.” Ibid. The agreement also provided:
“Any work performed in connection with the loading and discharging of containers for employer members of NYSA which is performed in the Port of Greater New York whether on piers or terminals controlled by them, or whether through direct contracting out, shall be performed by ILA labor at longshore rates.” Ibid.
After the 1959 agreement was reached, the development of container shipping accelerated. In 1967, ILA demanded in collective-bargaining negotiations that longshoremen stuff and strip all containers crossing the piers. Following a lengthy strike, ILA and NYSA in 1969 adopted, as part of their 1968-1971 collective-bargaining agreement, the Rules on Containers (Rules). The terms of that master agreement were adopted by other ports on the North Atlantic coast, including Hampton Roads and Baltimore. The Rules were slightly modified in 1971, after another long strike. In 1973 ILA and the Council of North Atlantic Shipping Associations (CONASA) executed the “Dublin Supplement” as an “interpretive bulletin” to the Rules. The substance of the Dublin Supplement was incorporated in the version of the Rules contained in the 197L-1977 collective-bargaining agreement.
In essence, the Rules contained in the 1968 and 1971 agreements provided that if containers owned or leased by the shipping companies and carrying LTL or consolidated container loads were to be stuffed or stripped within the local port area (that is, within a geographical radius of 50 miles of the port) by anyone other than the employees of the beneficial owner of the cargo, that work must be done at the piers by ILA labor. The shipping companies were required to pay a royalty on containers that passed over the piers intact, as well as liquidated damages, presently set at $1,000 per container, for any container handled in violation of the Rules. The Dublin Supplement declared that the Rules applied to all containers, including those designated as FSL containers, which were stuffed or stripped in the local area by other than the beneficial owner’s own employees. The Supplement also noted an exception for FSL containers warehoused locally for at least 30 days, and, as a method of enforcing the Rules, prohibited the employers from releasing any of their containers to known consolidators with facilities located within 50 miles of the port.
Thus, under the final version of the Rules incorporated in the 1974 agreement, if containers owned or leased by the shipping companies are to be stuffed or stripped locally by anyone other than the employees of the beneficial owner of the cargo, that work must be done at the piers by ILA labor. FSL containers that are transported intact to or from the beneficial owner or that are warehoused locally for 30 days, and consolidated containers coming from or bound for points outside the local area, do not have to be stuffed and stripped by ILA members. The practical effect of the Rules is that some 80% of containers pass over the piers intact. App. 612. The remaining 20% are stuffed and stripped by longshoremen, regardless of whether that work duplicates work done by non-ILA employees off-pier.
C
This case involves two proceedings before the National Labor Relations Board (Board) on charges that the Rules are illegal secondary activity in violation of federal labor law. The cases were consolidated on appeal. The Dolphin proceeding, 236 N. L. R. B. 525 (1978), concerns the application of the provisions on LCL cargo to containers used by consolidators operating within 50 miles of the Port of New York. The Associated Transport proceeding, 231 N- L. Ri B. 351 (1977), concerns the application of the Rules to FSL containers whose cargo was transferred by truckers to their own trucks within 50 miles of the Ports of Baltimore and Hampton Roads. The affected truckers and consolidators filed unfair labor practice charges with the Board, alleging that the Rules constituted a “hot cargo” agreement in violation of § 8 (e) of the National Labor Relations Act (Act) and that the activities of the parties to the agreement in enforcing its terms were an illegal secondary boycott prohibited by §8 (b)(4)(B) of the Act.
The facts underlying the charges may be briefly stated. Dolphin Forwarding, Inc. (Dolphin), and San Juan Freight Forwarding, Inc. (San Juan), were NVOCC consolidators, see n. 8, supra, soliciting business from shippers throughout the United States who wished to transport LCL cargo between New York and Puerto Rico. Dolphin and San Juan received their customers’ goods at their off-pier facilities, located within 50 miles of the Port of New York. Using subcontracted non-ILA labor, they consolidated the goods of two or more shippers, stuffed them into containers provided by members of NYSA, and had the filled containers trucked to the pier to be loaded onto ships by longshoremen. As a result of these practices, the NYSA members who had supplied their containers to the consolidators were assessed liquidated damages of approximately $47,000. Those carriers then informed Dolphin and San Juan that they would no longer furnish them with containers. Thereupon, Dolphin and San Juan filed unfair labor practice charges with the Board.
Houff Transport, Inc. (Houff), and Associated Transport, Inc. (Associated), were Interstate Commerce Commission-licensed common carriers who operated motor freight terminals within 50 miles of the Ports of Baltimore and Hampton Roads. Since the advent of containerization, they had transported PSL container loads to consignees both within and beyond the 50-mile radius, and routinely stripped such PSL containers and restuffed the cargo into their own vehicles for reasons of economy, safety, or state highway or bridge regulations.
The practice of using non-ILA labor to strip and restuff FSL cargo within the 50-mile radius is known as shortstop-ping. Although the Rules, prior to the Dublin Supplement, did not expressly discuss PSL cargo, see App. 235-250, 270-276, the ILA and the shipping companies apparently regarded shortstopping as an infraction, see 198 U. S. App. D. C., at 162, 613 P. 2d, at 895; 231 N. L. R. B., at 355 (Fanning, Chairman, dissenting). The Dublin Supplement, and subsequent versions of the Rules, provided that ILA labor must handle all PSL containers that otherwise would be handled within the local area by other than the consignee’s own employees, except for FSL cargo consigned to the beneficial owner’s place of business or warehoused for 30 days within the port area.
After the new Rules became effective, Houff and Associated shortstopped containers picked up from CONASA members. The shipping companies were assessed liquidated damages for each such container. When Houff and Associated refused to indemnify them for the fines, the shipping companies canceled their interchange agreements. Houff, Associated, and the Tidewater Motor Truck Association (TMTA), an association of which Associated was a member, filed unfair labor practice charges.
In holding that the charges were substantiated in both the Dolphin and Associated Transport proceedings, the Board relied on its previous decision in International Longshoremen’s Assn. (Consolidated Express, Inc.), 221 N. L. R. B. 956 (1975), enf’d, 537 F. 2d 706 (CA2 1976), cert, denied, 429 U. S. 1041 (1977) (hereinafter Conex) In Conex, the Board held that the traditional work of longshoremen has been to load and unload ships at the pier. As the Board explained in th& Dolphin proceeding, Conex
“held that the Rules were not valid work-preservation clauses in that traditionally the off-pier stuffing and stripping of containers was performed by consolidating companies and not longshoremen. Since the work was not traditional longshore work and had never been performed by longshoremen, the Rules which required the shipping companies to stop doing business with consolidators did not have a lawful work-preservation object.” 236 N. L. R. B., at 526.
Similarly, in the Associated Transport proceeding the Board affirmed the finding by the Administrative Law Judge (ALJ) of an unfair labor practice because longshoremen “had not historically done the work” of stripping FSL containers away from the pier. 231 N. L. R. B., at 353 (emphasis in original). In short, in the Board’s view the Rules sought to acquire for ILA members work that had historically been performed not by longshoremen but by employees of consolidators and truckers. . Therefore the Rules had a secondary objective forbidden by the Act.
ILA and CONASA appealed to the Court of Appeals, and the Board cross-applied for enforcement of its orders. The cases were consolidated. A divided panel of the Court of Appeals refused enforcement, holding that the Board had erred as a matter of law in defining the work in controversy. It therefore vacated the Board’s decisions, denied its applications for enforcement, and remanded the cases for further proceedings. We affirm.
II
Section 8 (b) (4) (B) of the Act prohibits unions and their agents from engaging in secondary activities whose object is to force one employer to cease doing business with another. Section 8 (e) makes unlawful those collective-bargaining agreements in which the employer agrees to cease doing business with any other person. Although § 8 (e) does not in terms distinguish between primary and secondary activity, we have held that, as in §8 (b)(4)(B), Congress intended to reach only agreements with secondary objectives. See NLRB v. Pipefitters, 429 U. S. 507, 517 (1977) (hereinafter Pipefitters); National Woodwork Manufacturers Assn. v. NLRB, 386 U. S. 612, 620, 635 (1967) (hereinafter National Woodwork).
Among the primary purposes protected by the Act is “the purpose of preserving for the contracting employees themselves work traditionally done by them.” Pipefitters, supra, at 517. Whether an agreement is a lawful work preservation agreement depends on “whether, under all the surrounding circumstances, the Union's objective was preservation of work for [bargaining unit] employees, or whether the [agreement was] tactically calculated to satisfy union objectives elsewhere. . . . The touchstone is whether the agreement or its maintenance is addressed to the labor relations of the contracting employer vis-a-vis his own employees.” National Woodwork, supra, at 644-645 (footnotes omitted). Under this approach, a lawful work preservation agreement must pass two tests: First, it must have as its objective the preservation of work traditionally performed by employees represented by the union. Second, the contracting employer must have the power to give the employees the work in question — the so-called “right of control” test of Pipefitters, supra. The rationale of the second test is that if the contracting employer has no power to assign the work, it is reasonable to infer that the agreement has a secondary objective, that is, to influence whoever does have such power over the work. “Were the latter the case, [the contracting employer] would be a neutral bystander, and the agreement or boycott would, within the intent of Congress, become secondary.” National Woodwork, supra, at 644-645.
In applying the work preservation doctrine, the first and most basic question is: What is the “work” that the agreement allegedly seeks to preserve? Sometimes the process of identifying the work at issue will require no subtle analysis. In National Woodwork, for example, the agreement preserved for the carpenters employed by a general contractor the work of fitting all doors installed on the jobsite. This was work they had always done, and the method the parties chose to preserve the carpenters’ right to that work was simply to prohibit the employer from purchasing any doors that had been prefitted by any other employees. That the provision incidentally required the employer to boycott all prefitted doors was of no consequence to the validity of the agreement. See Pipefitters, supra, at 510, 526.
But in many cases it is not so easy to find the starting point of the analysis. Work preservation agreements typically come into being when employees’ traditional work is displaced, or threatened with displacement, by technological innovation. The national labor policy expresses a preference for addressing “the threats to workers posed by increased technology and automation” by means of “labor-management agreements to ease these effects through collective bargaining on this most vital problem created by advanced technology.” National Woodwork, supra, at 641, 642, In many instances, technological innovation may change the method of doing the work, instead of merely shifting the same work to a different location. One way to preserve the work of the employees represented by the union in the face of such a change is simply to insist that the innovation not be adopted and that the work continue to be done in the traditional way. The union in National Woodwork followed this tactic and negotiated an agreement in which the employer agreed not to use prefabricated materials. We held that agreement was lawful under §§8 (e) and 8 (b)(4)(B). But the protection Congress afforded to work preservation agreements cannot be limited solely to employees who respond to change with intransigence. Congress, in enacting § 8 (e), did not intend to protect only certain kinds of work preservation agreements; rather, it “had no thought of prohibiting agreements directed to work preservation,” National Woodwork, supra, at 640. The work preservation doctrine, then, must also apply to situations where unions attempt to accommodate change while preserving as much of their traditional work patterns as possible. When this is the case the inquiry must be more refined and the analysis more discriminating.
The Board held that “ '[t]he traditional work of the longshoremen represented by ILA has been to load and unload ships. When necessary to perform their loading and unloading work, longshoremen have been required to stuff and strip containers on the piers.’ ” 231 N. L. R. B., at 364 (decision of ALJ, adopted by the Board), quoting Conex, 221 N. L. R. B., at 959; see 236 N. L. R. B., at 526. The Board then determined that the work in controversy was “the off-pier stuffing and stripping of containers,” ibid.; see 231 N. L. R. B., at 364-365. Similarly, in Conex the Board stated: “It is clear from the record that the work in controversy here is the LCL and LTL container work performed by [the charging parties] at their own off-pier premises.” 221 N. L. R. B., at 959. Because ILA members had never performed such work, the ' Board concluded that the Rules were an illegal attempt to reach out and acquire work that was not within the union’s traditional work jurisdiction and which its members had never performed. We agree with the Court of Appeals that this approach to defining the work at issue was incorrect as a matter of law.
The Board’s approach reflects a fundamental misconception of the work preservation doctrine as it has been applied in our previous cases. Identification of the work at issue in a complex case of technological displacement requires a careful analysis of the traditional work patterns that the parties are allegedly seeking to preserve, and of how the agreement seeks to accomplish that result under the changed circumstances created by the technological advance. The analysis must take into account “all the surrounding circumstances,” National Woodwork, 386 U. S., at 644, including the nature of the work both before and after the innovation. In a relatively simple case, such as National Woodwork or Pipefitters, the inquiry may be of rather limited scope. Other, more complex cases will require a broader view, taking into account the transformation of several interrelated industries or types of work; this is such a case. Whatever its scope, however, the inquiry must be carefully focused: to determine whether an agreement seeks no more than to preserve the work of bargaining unit members, the Board must focus on the work of the bargaining unit employees, not on the work of other employees who may be doing the same or similar work, and examine the relationship between the work as it existed before the innovation and as the agreement proposes to preserve it.
The Board, by contrast, focused on the work done by the employees of the charging parties, the truckers and consolidators, after the introduction of containerized shipping. It found that work was similar to work those employees had done before the innovation, and concluded that ILA was trying to acquire the traditional work of those employees. That conclusion ignores the fact that the impact of containerization occurred at the interface between ocean and motor transport; not surprisingly, the work of stuffing and stripping containers is similar to work previously done by both longshoremen and truckers. The Board’s approach would have been entirely appropriate in considering an agreement to preserve the work of truckers’ employees, but it misses the point when applied to judge this contract between the ILA and the shipowner employers.
By focusing on the work as performed, after the innovation took place, by the employees who allegedly have displaced the longshoremen’s work, the Board foreclosed — by definition — any possibility that the longshoremen could negotiate an agreement to permit them to continue to play any part in the loading or unloading of containerized cargo. For the very reason the Rules were negotiated was that longshoremen do not perform that work away from the pier, and never have. Thus it is apparent that under the Board’s approach, in the words of the Court of Appeals, the “work preservation doctrine is sapped of all life.” 198 U. S. App. D. C., at 176, 613 F. 2d, at 909.
That this is so is vividly demonstrated by considering how different would have been the results in National Woodwork and Pipefitters if we had adopted the approach now chosen by the Board. In National Woodwork we held that carpenters could seek to preserve their traditional work of finishing blank doors at the construction jobsite by prohibiting the employer, a general contractor, from purchasing prefinished doors from the factory. If we had followed the Board’s current approach in analyzing the agreement, we would have defined the work in controversy as “the finishing of blank doors away from the construction site.” That work, of course, had never been done by the carpenters employed by the general contractor, but had been performed by the employees of the door manufacturers since before the adoption of the agreement. We would perforce have determined that the object of the agreement was work acquisition, not work preservation.
Similarly, Pipefitters involved an agreement between a subcontractor and a pipefitters’ union that pipe threading and cutting were to be performed on the jobsite. Relying on the agreement, the union refused to install climate-control units whose internal piping had been cut, threaded, and installed at the factory. The Board held that the provision was a lawful work preservation agreement, but that the refusal to handle the prepiped units was an unfair labor practice because the units had been specified by the general contractor and the subcontractor had no power to assign the employees the work they sought. Neither the Court of Appeals nor this Court questioned the validity of the work preservation clause but for the fact that it was enforced against an employer who could not control the work. Under the Board’s current approach, however, the “work” would have been “cutting, threading, and installing pipe in climate-control units at the factory.” Since the bargaining unit employees had never performed that work, there would have been no reason to reach the “right of control” issue.
Thus the Board’s determination that the work of longshoremen has historically been the loading and unloading of ships should be only the beginning of the analysis. The next step is to look at how the contracting parties sought to preserve that work, to the extent possible, in the face of a massive technological change that largely eliminated the need for cargo handling at intermediate stages of the intermodal transportation of goods, and to evaluate the relationship between traditional longshore work and the work which the Rules attempt to assign to ILA members. This case presents a much more difficult problem than either National Woodwork or Pipefitters because the union did not simply insist on doing the work as it had always been done and try to prevent the employers from using container ships at all— though such an approach would have been consistent with National Woodwork and Pipefitters. Instead, ILA permitted the great majority of containers to pass over the piers intact, reserving the right to stuff and strip only those containers that would otherwise have been stuffed or stripped locally by anyone except the beneficial owner’s employees. The legality of the agreement turns, as an initial matter, on whether the historical and functional relationship between this retained work and traditional longshore work can support the conclusion that the objective of the agreement was work preservation rather than the satisfaction of union goals elsewhere.
Respondents assert that the stuffing and stripping reserved for the ILA by the Rules is functionally equivalent to their former work of handling break-bulk cargo at the pier. Petitioners-intervenors, on the other hand, argue that containerization has worked such fundamental changes in the industry that the work formerly done at the pier by both longshoremen and employees of motor carriers has been completely eliminated.
These questions are not appropriate for initial consideration by reviewing courts. They are properly raised before the Board, whose determinations are, of course, entitled to deference. Since the Board has not had an opportunity to consider these questions in relation to a proper understanding of the work at issue, we will not address them here. We emphasize that neither our decision nor that of the Court of Appeals implies that the result of the Board’s reconsideration of this case is foreordained. Viewing the work allegedly to be preserved by the Rules from the proper perspective, the Board will be free to determine whether the Rules represent a lawful attempt to preserve traditional longshore work, or whether, instead, they are “tactically calculated to satisfy union objectives elsewhere,” National Woodwork, 386 U. S., at 644. This determination will, of course, be informed by an awareness of the congressional preference for collective bargaining as the method for resolving disputes over dislocations caused by the introduction of technological innovations in the workplace, see id., at 641-642. Thus, in judging the legality of a thoroughly bargained and apparently reasonable accommodation to technological change, the question is not whether the Rules represent the most rational or efficient response to innovation, but whether they are a legally permissible effort to preserve jobs.
If the Board finds, on remand, that the Rules have a lawful work preservation objective, it will then, of course, be obliged to consider the charging parties’ contention that CONASA members did not have the right to control the stuffing and stripping of containers. Because the Board held that the agreement was directed at work acquisition, rather than work preservation, it did not decide the right-to-control issue in this case. That issue remains open on remand. Therefore, and because the arguments of the parties were necessarily-addressed to an erroneous conception of the work whose control was disputed, any discussion of that issue here would be premature. Respondents have also argued that the employers, as common carriers who are subject to Government regulation and to the provisions of their own tariffs, shippers’ bills of lading, and intermodal interchange agreements with motor carriers, have no legal right to withhold containers or container services from their customers on a selective basis, to condition access to the containers on compliance with the Rules, to seek indemnification from their customers for fines imposed under the Rules, or to enforce the Rules after the containers have been released to motor carriers. See, e. g., Shipping Act, 1916, 46 U. S. C. §801 et seq.; Intercoastal Shipping Act, 1933, 46 U. S. C. § 843 et seq.; Sea-Land Service, Inc.-Proposed ILA Rules on Containers, 20 F. M. C. 788 (1978), review pending, No. 78-1776 (CADC). These contentions present difficult and complex problems which are not properly before us.
We conclude that the Court of Appeals correctly held that the Board’s definition of the work in controversy in this dispute was erroneous as a matter of law, and we therefore affirm the Court of Appeals’ judgment vacating the Board’s decisions, denying the applications for enforcement, and remanding to the Board for further proceedings.
It is so ordered.
APPENDIX TO OPINION OF THE COURT
1974 Rules on Containers
CONASA-ILA RULES ON CONTAINERS PREAMBLE
This Agreement made and entered into by and between the carrier and direct employer members of the CONASA Port Associations (hereinafter referred to collectively as “CONASA”) and the International Longshoremen’s Association, AFL-CIO (“ILA”), its Atlantic Coast District (“ACD”) and its affiliated local unions in each CONASA port (“locals”) covers all container work at a waterfront facility which includes but is not limited to the receiving and delivery of cargo, the loading and discharging of said cargo into and out of containers, the maintenance of containers, and the loading and discharging of containers on and off ships.
CONASA agrees that it will not directly perform work done on a container waterfront facility (as hereinafter defined) or contract out such work which historically and regularly has been and currently is performed by employees covered by CONASA-ILA Agreements, including CONASA-ILA craft agreements, unless such work on such container waterfront facility is performed by employees covered by CONASA-ILA Agreements.
RULES
The following provisions are intended to protect and preserve the work jurisdiction of longshoremen and all other ILA crafts which was performed at deepsea waterfront facilities. These rules do not have any effect on work which historically was not performed at a waterfront facility by deepsea ILA labor. To assure compliance with the collective bargaining provisions, the following rules and regulations shall be applied uniformly in all CONASA Ports to all imports or export cargo in containers:

(4) Consolidated container loads of mail, household effects of a person who is relocating his place of residence, with no other type of cargo in the container, or personal effects of military personnel.
B. Import Cargo:
(1) All cargo discharged from containers outside the “geographic area”.
(2) Containers discharged at a qualified consignee’s facility by its own employees.
(3) Consolidated container loads of mail, household effects of a person who is relocating his place of business, with no other type of cargo in the container, or personal effects of military personnel.
(4) Containers of a qualified consignee discharged at a bona fide public warehouse within the “geographic area” which comply with all of the following conditions.
1. The container cargo is warehoused at a bona fide public warehouse.
2: The qualified consignee pays the normal labor charges in and out; and the normal warehouse storage fees for a minimum period of thirty or more days, and;
3. The cargo being warehoused (a) in the normal course of the business of the qualified consignee; (b) title to such goods has not been transferred from the qualified consignee to another.
The carrier on request will furnish all documentation and other information which permits the Container Committee in the port to determine whether conditions 1, 2 and 3 have been met. This exception shall not apply where cargo is warehoused for the purpose of avoidance or evasion of Rule 1. It is limited to containers warehoused as provided in the above conditions and any warehouse which does not conform to such conditions shall be deemed a consolidator or deconsolidator.
Rule 3 — Batching
When an employer-member or carrier uses a trucker to remove or deliver containers in batches, or in substantial number, from or to a terminal to another place of rest (outside of its terminal) where containers are stored pending their delivery to a consignee (or after being received from a shipper and while waiting the arrival of a ship), for the purpose of reducing the work jurisdiction of the ILA or any of its crafts, such use is deemed to be batching and an evasion of these Rules in violation of the CONASA-ILA contract.
Rule 4 — Headload
Where a single qualified shipper sends an export container which contains all of his own cargo to a waterfront facility and such container is not full, the carrier or direct employer may load this container with additional cargo at the waterfront facility. On import cargo, the carrier or direct employer may discharge any such additional cargo and send the remaining cargo in the container to the qualified consignee. The loading or discharging of cargo at ILA ports shall be performed at a waterfront facility by deepsea ILA labor.
Rule 5 — Overland Movement of Containers from CONASA Port to Non-CONASA Port
If a carrier moves containers from a CONASA Port to a non-CONASA Port for the purpose of evading the Rules on Containers, the carrier is in violation of the CONASA-ILA Agreement. If the cargo is being moved to a non-CONASA-ILA Port in the normal course of business, and not for the purpose of evasion, then such movement is not a violation.
Rule 6 — Importers Advertising Evasion of Rules
The circulation, in writing, by importers of methods developed by them to evade the Rules on Containers by issuing single bills of lading on what are in fact consolidated container loads shall be deemed a violation and all CONASA-ILA Container Committees shall be advised to stop such evasion at the waterfront facilities.
Rule 7 — No Avoidance or Evasion
The above rules are intended to be fairly and reasonably applied by the parties. To obtain non-diseriminatory and fair implementation of the above, the following principles shall apply:
(a) Geographic Area — Agreement in the Port to the geographic area as provided in Rule 1 is based on present consolidated movement patterns in the port. Should any person, firm or corporation for the purpose of evading the provisions of the Rules on Containers, seek to change such pattern by shifting its operations to, or commencing new operations at, a point outside said agreed upon geographic area, then either party may raise the question whether said point should be included within the said geographic area, and upon agreement that the purpose of the shift in its operations was to evade the provisions of the Rules on Containers, then said point shall be deemed to be within the said geographic area for the purpose of these rules.
(b) Containers Owned, Leased or Used — Containers owned, leased or nsed by companies which are affiliated either directly or through a holding company with a carrier or a direct employer shall be deemed to be containers owned, leased or used by a carrier or direct employer. Affiliation shall include subsidiaries and/or affiliates which are. effectively controlled by the carrier or direct employer, its parent, or stockholders of either of them.
(c) Liquidated Damages — Failure to load or discharge a container as required under these rules will be considered a violation of the contract between the parties. Use of improper, fictitious or incorrect documentation to evade the provisions of Rule 1 and Rule 2 shall also be considered a violation of the contract. If for any reason a container is no longer at the waterfront facility at which it should have been loaded or discharged under the Rules, then the carrier or its agent or direct employer shall pay, to the joint Container Royalty Fund, liquidated damages of $1,000 per container which should have been loaded or discharged. If any carrier does not pay liquidated damages within 30 days after exhausting its right to appeal the imposition of liquidated damages to the Committee provided in Rule 9 (a) below, the ILA shall have the right to stop working such carrier’s containers until such damages are paid.
(d) Any facility operated in violation of the Container Rules will not have service supplied to it by any direct employer and the ILA will not supply labor to such facility.
Rule 8 — Renegotiation and Cancellation — No Arbitration
These Rules shall be in effect for the term of the CONASA-ILA Agreement, provided, however, that either party shall have the right to cancel the Rules on Containers at any time on or after December 1, 1974, on thirty (30) days written notice of a desire to renegotiate the provisions of these Rules. Negotiations shall be held during such thirty (30) day period and if the parties are unable to agree by the end of such period, these Rules shall be deemed cancelled. Thereafter, the ILA shall have the right to refuse to handle containers and CONASA shall have the right to refuse to hire employees under the said Rules. The negotiations referred to above shall, under no condition, be subject to the grievance or arbitration provisions of any CONASA-ILA Agreement.
Rule 9 — Enforcement of the Rules on Containers
To assure effective, fair and non-discriminatory enforcement of the above Rules, the following regulations shall apply:
(a) A Committee in each CONASA port represented equally by management and union shall be formed and shall have the responsibility and power to hear and pass judgment on any violations of these Rules. Any inability to agree shall be processed as a grievance under the applicable contract except as limited by Rule 8 hereof. A joint committee, known as the CONASA-ILA Container Committee, represented equally by management and labor and made up of representatives (to be mutually agreed upon) from each CONASA Port, namely, Boston, Rhode Island, New York, Philadelphia, Baltimore and Hampton Roads shall meet at least quarterly each year for the purpose of insuring uniformity in the interpretation of these Rules.
(b) A Committee of carriers, together with CONASA-ILA Container Committee will develop uniform documentation which shall be required to be prepared and maintained by all carriers in order to readily identify all Rule 1 containers which are subject to loading or discharging by deepsea ILA labor. It shall be the obligation of employer-members to clearly mark each con-tamer’s documentation as to whether or not it is a Rule 1 container, which shall be loaded or discharged. If a container’s documentation is not clearly marked, it shall be deemed a Rule 1 container and it shall be loaded or discharged by deepsea ILA labor at the waterfront facility. With respect to all containers received at or delivered from the waterfront facility, a record of the same shall be made by ILA Checkers or Clerks. All carriers will distribute to all other carriers any and all information and devices which are being used by any person to circumvent the Rules on Containers. Any carrier whose attention is brought to a violation of the Rules shall immediately cease such violation and report the matter to the appropriate CONASA-ILA Container Committee and to the policing agency provided in (e) below in its port.
(c) Every import container destined to a point within 50-miles of a CONASA Port shall be delivered only on a delivery order. Every export container coming from a point within 50-miles of a CONASA Port shall be received only on a dock/cargo receipt. Such delivery orders and doek/cargo receipts shall certify the place of delivery and origin of the container, the name or names of the person to whom the cargo is being delivered and from which it is shipped, the identity of the owner of the cargo, weight of the cargo, identity of the cargo and the origin and final destination of the container. Copies of such delivery orders and dock/cargo receipts shall be available to the local port Container Committee and the policing agency provided for in (e) below.
(d) The Container Committee in each CONASA Port shall promulgate to all carriers and direct employers, and to the Container Committees in each CONASA Port, any and all interpretations of the Rules on Containers as and when they are made. This will include uniform interpretations as and when they are issued. The CONASA-ILA Container Committee shall also promulgate uniform interpretations to local port Container Committees, as and when they are issued.
(e) Policing Agency — Each CONASA Port shall establish a method of policing and enforcing these Rules on a uniform and non-discriminatory basis. No such method shall be implemented until presented to and approved by the joint CONASA-ILA Container Committee.
Rule 10 — Container Royalty Payments
The two Container Royalty payments required by the CONASA-ILA collective bargaining agreements shall be payable only once in the Continental United States. They shall be paid in that ILA Port where the container is first handled by ILA longshore labor at longshore rates. The second container royalty payment (provided by paragraph 6 of the 1971-1974 CONASA-ILA Memorandum of Agreement) shall be continued and shall be used for fringe benefit purposes only, other than supplemental cash benefits, which purposes are to be determined locally on a port by port basis. Containers originating at a foreign port which are transshipped at a United States port for ultimate destination to another foreign port (“foreign sea-to-foreign-sea containers”) are exempt from the payment of container royalties.
A contrary result was reached in International Longshoremen’s Assn., Local 1675 v. NLRB, 560 F. 2d 439 (CA1 1977), and in International Longshoremen’s Assn. v. NLRB, 537 F. 2d 706 (CA2 1976), cert. denied, 429 U. S. 1041 (1977). Cf. Humphrey v. International Longshoremen’s Assn., 548 F. 2d 494 (CA4 1977).

The longshore unit in the Port of New York was certified by the National Labor Relations Board as
“[a] 11 longshore employees engaged in work pertaining to the rigging of ships, coaling of same, loading and unloading of cargoes, including mail, ships’ stores and baggage, handling lines in connection with the docking and undocking of ships, including hatch bosses; cargo repairmen, checkers, clerks and timekeepers and their assistants, including head receiving and delivery clerks; general maintenance, mechanical and miscellaneous workers; horse and cattle fitters, grain ceilers, and marine carpenters, in the Port of Greater New York and vicinity. . .

A freight consolidator combines the goods of various shippers into a single shipment at its own off-pier terminal and delivers the shipment to the pier. Ordinarily, consolidators operate no transportation of their own except for pickup and delivery equipment. They contract with carriers, such as truckers and steamship lines, for the actual transportation of the goods. See Comment, Intermodal Transportation and the Freight Forwarder, 76 Yale L. J. 1360, 1362 (1967). A’ consolidator who acts as a carrier by arranging for the transportation of goods from port to port is called a nonvessel operating common carrier by water (NVOCC), and is regulated by the Federal Maritime Commission. See Federal Maritime Commission, Preliminary Staff Report on Non-Vessel Operating Common Carriers by Water (Dec. 8, 1970)see generally Ullman, supra n. 2.
See, e. g., 198 U. S. App. D. C., at 159, 613 F. 2d, at 892; Ross, supra n. 3, at 400.
The longshoremen involved in this dispute are represented by the ILA. Their employers, shipowners and stevedoring companies operating in the Ports of New York, Baltimore, and Hampton Roads, belong to several employers’ organizations. These include the New York Shipping Association (NYSA), the Steamship Trade Association of Baltimore (STAB), and the Hampton Roads Shipping Association (HRSA). Since 1970, the Council of North Atlantic Shipping Associations (CONASA), a multiem-ployer bargaining association representing shipping associations including NYSA, STAB, and HRSA, has bargained with ILA on a master-contract basis.
The first specially fitted container ship began operating in the late 1950’s between New York and Puerto Rico. See App. 117. As late as 1966, the percentage of general cargo moved by containers in the Port of New York was only 3%. See Ross, supra n. 3, at 398. The first container ships did not appear in the Ports of Baltimore and Hampton Roads until 1965 and 1966. See 198 U. S. App. D. C., at 161, 613 F. 2d, at 894; International Longshoremen’s Assn. (Associated Transport, Inc.), 231 N. L.R.B. 351, 359 (1977).
The 1974 Rules are reproduced in the appendix to this opinion.
The 1968 and 1971 versions of the Rules referred only to containers “owned or leased” by the employers, see App. 237, 238, 247, 272, 273. The 1974 agreement refers to containers “owned, leased or used by carriers.” See infra, at 514. There is nothing in the record to indicate that the fines which led to the unfair labor practice charges before us were imposed for infractions relating to containers which were not owned or leased by CONASA members. Therefore we, like the Board and the Court of Appeals, assume that the Rules have application only to containers that belong to the contracting employers. See 198 U. S. App. D. C., at 179, 613 F. 2d, at 912; 236 N. L. R. B., at 526; 231 N. L. R. B., at 359; International Longshoremen’s Assn. (Consolidated Express, Inc.), 221 N. L. R. B. 956, 958, 959 (1975); but see 231 N. L. R. B., at 353, n. 3 (Fanning, Chairman, dissenting).
Dolphin has since ceased doing business in New York.
Dolphin began such operations several years before the adoption of the Rules. The NYSA members contended that they supplied containers to Dolphin only because it listed Massachusetts as the point of origin for the containers rather than the actual facility within the port area. San Juan was established in 1972, several years after the Rules were first adopted. It apparently listed Chicago as the point of origin of containers it shipped. 198 U. S. App. D. C., at 166, 613 F. 2d, at 899.
Associated is no longer in business.
The Rules were first litigated in 1970 when the United States Court of Appeals for the Second Circuit rejected a claim that their enforcement violated the antitrust laws. The Court of Appeals held that the Rules came under the labor exemption. Intercontinental Container Transport Corp. v. New York Shipping Assn., 426 F. 2d 884 (1970). The plaintiff in the antitrust proceeding also initiated related unfair labor practice proceedings before the Board by filing unfair labor practice charges alleging violations of §§ 8 (e) and 8 (b) (4) (B). The Regional Director’s dismissal of the charges, on the ground that the Rules were a valid work preservation agreement, was affirmed on appeal by the Board’s General Counsel. App. 621.
Houff intervened on appeal, and TMTA and Dolphin were permitted to intervene after the Court of Appeals issued its decision.
Section 8 (b), as set forth in 29 U. S. C. § 158 (b), provides in pertinent part:
“It shall be an unfair labor practice for a labor organization or its agents—
“(4) (ii) to threaten, coerce, or restrain any person engaged in commerce or in an industry affecting commerce, where ... an object thereof is—
“(B) forcing or requiring any person to cease using, selling, handling, transporting, or otherwise dealing in the products of any other producer, processor, or manufacturer, or to cease doing business with any other person . . . Provided, That nothing contained in this clause (B) shall be construed to make unlawful . . . any primary strike or primary picketing. . . .”
Section 8 (e), as set forth in 29 U. S. C. § 158 (e), provides in pertinent part:
“It shall be an unfair labor practice for any labor organization and any employer to enter into any contract or agreement, express or implied, whereby such employer ceases or refrains or agrees to cease or refrain from handling, using, selling, transporting or otherwise dealing in any of the products of any other employer, or to cease doing business with any other person, and any contract or agreement entered into heretofore or hereafter containing such an agreement shall be to such extent unen-forcible and void. . . .”
See Comment, Work Recapture Agreements and Secondary Boycotts: ILA v. NLRB (Consolidated Express, Inc.), 90 Harv. L. Rev. 815 (1977).
The effect of work preservation agreements on the employment opportunities of employees not represented by the union, no matter how severe, is of course irrelevant to the validity of the agreement so long as the union had no forbidden secondary purpose to affect the employment relations of the neutral employer. See Pipefitters, 429 U. S., at 510, 526.
We need hardly add that the analysis is not, as the parties have sometimes seemed to suggest, simply a matter of deciding whether a container is more like the hold of a ship or more like a big box. The usefulness of a container lies precisely in the fact that it may function as an integral part of the hold while it is aboard a vessel, as a trailer when it is transported by truck, and as part of a railroad car when it is carried by rail.
Obviously, the result will depend on how closely the parties have tailored their agreement to the objective of preserving the essence of the. traditional work patterns. Thus the claim that if the Rules are upheld the union would be able to follow containers around the country and assert the right to stuff and strip them far inland is groundless. That work would bear an entirely different relation to traditional longshore work, and would require a wholly different analysis.
They contend that there is no significant economic advantage to be gained from containerization over break-bulk handling at the pier when the stuffing and stripping is to be done locally.
The dissenting opinion of The Chief Justice proceeds on the assumption that we decide today the proper definition of the work in controversy, see post, at 528, and hold that the Rules are a lawful work preservation agreement, see post, at 525, 528-529. Our holding, we repeat, is that the Board’s definition of the work in controversy was erroneous as a matter of law. The question whether the Rules may be sustained under a proper understanding of the work preservation doctrine must be answered first by the Board on remand.
It is plain that the outcome of the right-to-control test will be significantly affected by whether the work in controversy is viewed as the stuffing and stripping done at the off-pier facilities of truckers and consolidators by their own employees or as, for example, the stuffing and stripping of certain types of cargo from containers owned or leased by, and in the possession and control of, the shipping companies.
What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.
