Industrial action refers to any form of protest or strike taken by workers in order to express their dissatisfaction with certain conditions, such as wages, working hours, or other employment-related issues. This can include a wide range of actions, from peaceful demonstrations and picketing to more disruptive tactics like sit-ins, slowdowns, or even complete shutdowns of production. The term is often used in the context of labor disputes between workers and their employers, but it can also refer to action taken by other groups, such as students or professionals, in pursuit of common goals.
