Explanation:

Measures taken by the workforce that will halt or slow output, in order to put pressure on management during an industrial dispute, e.g.: strike, work-to-rule, overtime ban and go-slow.

There are three main forms of industrial action:

• strike - where workers refuse to work for the employer.
• action short of a strike - where workers take action such as working to rule, go slows, overtime bans or callout bans.
• lock-out - a work stoppage where the employer stops workers from working.
