Records About Worker-Initiated Strikes and Employer-Initiated Lockouts

The data were compiled and published each year. This series contains records of worker-initiated strikes and lockouts of workers by their employers that involved six workers or more and continued for the equivalent of a full day or shift or longer.

The agency did not attempt to distinguish between strikes and lockouts and referred to both collectively as "work stoppages." Information includes data collected through avail able news sources and verified by the parties where possible. Information was regularly received from the Federal Mediation and Conciliation Service and state labor-related agencies. Each record is a work stoppage case with a unique case number made up of the year in which the stoppage began, the month in which the stoppage began, and the stoppage number within the month.
