A work stoppage is a strike or a lockout.
A strike is a temporary stoppage of work by a group of workers (not necessarily union members) to express a grievance or enforce a demand. A strike is initiated by the workers of an establishment.
A lockout is a temporary withholding or denial of employment during a labor dispute in order to enforce terms of employment upon a group of employees. A lockout is initiated by the management of an establishment.
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.
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.
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.
"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.
The Federal Mediation and Conciliation Service issues a monthly report showing all work stoppages. The data are available at http://www.FMCS.gov.
