Concepts and definitions

Stoppages of work

A strike, lockout or other stoppage.

Strike

The cessation of work by a body of persons employed, acting in combination, or a concerted refusal or a refusal under a common understanding of any number of persons employed to continue to work for an employer, or a concerted interruption of work or performance of work on a go-slow basis by any number of employees, done as a means of compelling their employer or any person or body of persons employed, to accept or not to accept terms or conditions of or affecting employment.

Lockout

The closing of a place of employment, or the suspension of work, or the refusal by an employer to continue to employ any number of persons employed by him, done in consequence of a trade dispute, not with the intention of finally determining employment, but with a view to compelling those persons employed by him, to accept terms or conditions of or affecting employment.

The definitions are taken from the permanent Labour Tribunal Act.

Methods of measurement

Strikes and lockouts

The basic unit of measurement used to record a strike or lockout is the economic unit (industry or undertaking). 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 are counted as one strike or lockout. Those arising from the same case of dispute, but occurring at different times in different establishments of the same enterprise are counted as separate strikes or lockouts. Stoppages resulting from the same case of dispute, occurring in establishments of different enterprises, either simultaneously or at different times, are also counted as separate strikes or lockouts.

Economic units involved

The economic unit involved is the industry or undertaking, defined as any registered undertaking which is concerned with the production of goods and services.

Workers involved

The number of workers involved refers to the number of employees working, taking into consideration the reasons for those absent.

Duration

The duration is measured in workdays from the date the strike or lockout began to the date it terminated in the economic unit concerned.

Time not worked

Total time not worked, in workdays, is the product of the number of workers involved and the duration. Time not worked is measured for all workers involved, directly or indirectly. Overtime is not taken into account.
