Work Stoppages: Design

The Work Stoppages program is fundamentally different from most U.S. Bureau of Labor Statistic (BLS) programs because it does not provide data from a survey. BLS compiles data on work stoppages—strikes or lockouts—involving 1,000 or more workers for at least a full day or shift. Information on work stoppages is obtained from major media sources, reports from the Federal Mediation and Conciliation Service, state labor market information offices, and BLS Strike Reports from the Office of Employment and Unemployment Statistics. Work stoppages data have been collected consistently since 1947, with detailed information available since 1993.

Detailed data on work stoppages include monthly and annual listings of companies and state and local governments involved in a work stoppage are available at www.bls.gov/wsp. For an in-depth discussion of program concepts and measures, see the work stoppages concepts and calculation sections.
