A sitdown strike, also known as a work-in or occupation, involves employees occupying their place of work and refusing to work until their demands are met. However, there are several other synonyms for this labor tactic. A work stoppage refers to any organized cessation of work by employees, including strikes and lockouts. A wildcat strike is an unauthorized strike taken by employees without the approval of their union. A sit-in also involves occupying a space, but it is typically nonviolent and used for protests instead of labor disputes. Finally, a slowdown is a deliberate reduction in work output, often used as a bargaining tactic in labor negotiations.
