work to rule

Meaning

A form of industrial action (similar to a strike) where employees do exactly what is written in their contracts and safety regulations, and absolutely nothing more. By refusing to work overtime, answer emails out of hours, or perform extra tasks, they slow down operations while remaining legally protected. It is a formal term used in labor relations and union negotiations.
