Methods of measurement

Strikes and lockouts

The basic unit of measurement used to record a strike or lockout is the economic unit. The resumption of a strike or lockout that is interrupted but later recommences, still due to the same case of dispute, is counted as a continuation of the original strike or lockout.

Work stoppages arising from the same case of dispute, occurring simultaneously in different establishments of the same enterprise are counted as the same strike or lockout. Those arising from the same case of dispute, occurring at different times in different establishments of the same enterprise are counted separately. Work stoppages arising from the same case of dispute, occurring simultaneously or at different times in establishments of different enterprises are also counted as separate strikes or lockouts.

Economic units involved

The economic unit is the establishment, firm, enterprise, local workplace, industry or government-owned company. An establishment is defined as an organization employing five or more persons for the production and distribution of goods and services.

Workers involved

The number of workers involved is the maximum number of workers that took part during the course of the stoppage, even if some workers participated for only part of the duration.

Duration

The duration is measured in workdays in one economic unit.

Time not worked

Total time not worked, measured in workdays, is the product of the number of workers involved and the duration. Overtime is not included.
