Industrial action or job action refers collectively to any measure take by trade unions or other organised labour meant to reduce productivity in a workplace. Quite often it is used and interpreted as a euphemism for a strike or mass strike but the scope is much wider. Industrial action may take place in the context of a labour dispute or may be meant to effect political or social change. Specifically industrial action may include one or more of the following: Strike, occupation of factories, shut down, overtime ban.
