What action does a strike involve?

A strike is primarily defined as a refusal to work as a form of protest. This action is usually taken by workers or labor unions to express dissatisfaction with working conditions, pay, or other employment-related issues. By halting work, employees aim to leverage their collective power to prompt employers to address their grievances. This method has been a significant tool throughout labor history, allowing workers to assert their rights and seek better conditions or compensation.

The other options reflect different types of actions or strategies that are not directly related to the concept of a strike. Negotiation for better pay, for example, involves discussions and bargaining, rather than a collective cessation of work. Endorsing a candidate pertains to political actions rather than labor disputes. Legal actions against an employer might involve lawsuits or formal complaints but do not encapsulate the essence of a strike, which revolves around collective action and the withdrawal of labor.
