Employment

The Age Discrimination in Employment Act of 1967 (ADEA) (29 U.S.C. § 621 to 29 U.S.C. § 634) is a federal law that provides certain employment protections to workers who are over the age of forty, who work for an employer who has twenty or more employees. For protected workers, the ADEA prohibits discrimination at all levels of employment, from recruitment and hiring, through the employment relationship, and through decisions for layoffs or termination of the employment relationship. An age limit may only be legally specified for protected workers in the circumstance where age has been shown to be a " bona fide occupational qualification reasonably necessary to the normal operation of the particular business" (see 29 U.S.C. § 623(f)(1)). In practice, BFOQs for age are limited to the obvious (hiring a young actor to play a young character in a movie), when a job is physically demanding (police, firefighters, military service), or when public safety is a concern (for example, in the case of age limits for pilots, truck drivers, and bus drivers).
