Methods of measurement

Strikes and lockouts

The basic unit of measurement used to record a strike or lockout is the case of dispute. 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 new strike or lockout.

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

Economic units involved

The economic unit is the establishment, defined as a unit which engages in an economic activity in one particular place or location, operated or directed by a single management or legal entity.

Workers involved

The number of workers involved is the average of the number of daily absences during the period of the strike or lockout. Part-time workers are counted as individuals on the same basis as full-time workers.

Duration

The duration is measured in workdays from the date the strike or lockout began in the first economic unit involved up to the date it terminated in the last one.

Time not worked

Total time not worked is measured in workdays as the product of the number of workers involved and the duration. The shorter working hours of part-time workers are not taken into account, nor is overtime.
