What form of protest occurs when employees occupy the workplace and refuse to leave?

The correct answer is characterized as a "Sit In." This form of protest involves individuals occupying a space, particularly in a workplace, and remaining there to convey their discontent or to demand specific changes. This tactic is often used to draw attention to various issues, such as working conditions, pay disputes, or other grievances.

Sit Ins are effective because they disrupt normal operations and create a visible presence that highlights the employees' dissatisfaction. By occupying the workplace, employees can put pressure on management to negotiate or address their concerns. This method has historical roots in various social justice movements, where it has been used to challenge authority and advocate for rights.

While the other options may represent other forms of protest, they do not specifically describe the act of occupying a space in this way. Demonstrations typically involve public gatherings to express views, strikes refer to a work stoppage, and occupy actions may refer to broader societal movements that can include but are not limited to sits in. However, in the context of the specific question, “Sit In” effectively describes the act of occupying a workplace and refusing to leave as a form of protest.
