Description of Measures Work stoppage data are published quarterly and annually. Quarterly information is available in the publication, Compensation and Working Conditions, both in paper form and online . Annual information is available in an annual news release both in paper form and online . It includes the above data for work stoppages of 5,000 workers or more and the historical table. Reports are compiled from news reports and direct contacts with labor or management representatives.
Work stoppages are strikes or lockouts.
A lockout is a temporary withholding or denial of employment during a labor dispute to enforce terms of employment upon a group of employees. Days of idleness are the aggregate number of work days lost as a result of a work stoppage. It is calculated by multiplying the number of workers involved in the stoppage by the number of days the stoppage is in effect. Aggregate figures are the result of summing all products thus obtained. Number of workers includes all workers made idle for one shift or longer in establishments directly involved in a stoppage.
