Work Stoppages

Work Stoppages Technical Notes

The Bureau of Labor Statistics provides information on major (1,000 workers or more) work stoppages in the United States. The number of workers includes those idled for one shift or longer in the establishment(s) directly involved in the dispute as well as those in the establishment idled for related reasons, such as their facility is closed down during the stoppage. An attempt is made to contact the parties involved in the work stoppage (employer, employer group, or union) to determine whether the duration and number of workers idled by the stoppage meet the thresholds for inclusion in this report. For additional information on the concepts, data sources, design, measures, and history of the work stoppages program, see the Work Stoppages Handbook of Methods.

Detailed monthly work stoppage data from 1993 are available and include organization(s) involved, location, beginning and ending dates, the number of workers, and total days of idleness.

Annual historical major work stoppages data from 1947 are available and include the number of work stoppages, workers, and total days of idleness.

Historical work stoppages publications from 1936 to 1979 are also available.
