refusal to work or perform

refusal to work or perform

If an employee or service provider declines to perform the function for which he or she was engaged, that is a "refusal to work." In the context of workplace safety and health, if an employee believes that death, serious injury, or debilitating illness is likely to result from performing the assigned task, that employee may have a legal right to refuse to perform the work. Such a situation is often called "refusal to work" for short. Refusal to work may also occur as part of a labor action. Then it is often called a strike.
