The Work Stoppages program provides monthly and annual data and analysis of major work stoppages involving 1,000 or more workers lasting one full shift or longer. The monthly and annual data show the establishment and union(s) involved in the work stoppage along with the location, the number of workers, and the days of idleness. The monthly data lists all work stoppages involving 1,000 or more workers that occurred during the full calendar month for each month of the year. The annual data provides statistics, analysis, and details of each work stoppage of 1,000 or more workers that occurred during the year. See concepts within the Handbook of Methods for more information on work stoppage terms.
The work stoppages program reference period is the entire calendar month whereas the strike report reference period is the pay period that includes the 12th of the month. The BLS strike report includes strikes that cover 1,000 or more workers, the same as the work stoppages program.
Work days are defined as the weekdays Monday through Friday excluding Federal holidays. More information on work stoppage terms and concepts are available at www.bls.gov/opub/hom/wsp/home.htm.
The term "days idled this month" is the total number of working days lost during the work stoppage in the month multiplied by the number of workers participating in the work stoppage. See concepts within the Handbook of Methods for more information on work stoppage terms.
"Days idle, cumulative" is the total number of working days lost multiplied by the number of workers occurring over the entire span of the work stoppage, often over a period of months. See concepts within the Handbook of Methods for more information on work stoppage terms.
