On building construction and seasonal trades were put on a continuous six-day week, while factories that regularly halted production every month for maintenance were put on six- or seven-day continuous production weeks. In , it was reported that about 50 different versions of the continuous work week were in use, the longest being a 'week' of 37 days (30 continuous days of work followed by seven days of rest). By the end of 1929, orders were issued that the continuous week was to be extended to 43% of industrial workers by and to 67% by . Actual conversion was more rapid, 63% by . In it was decreed that the conversion of all industries was to be completed during the economic year , except for the textile industry. But on peak usage was reached, with 72.9% of industrial workers on continuous schedules. Thereafter, usage decreased. All of these official figures were somewhat inflated because some factories said they adopted the continuous week without actually doing so. The continuous week was applied to retail and government workers as well, but no usage figures were ever published.Solomon M. Schwarz, Labor in the Soviet Union (New York: Praegar, 1951) 258–277.
