Which of the following circumstances would not be covered under workers' compensation?

In the context of workers' compensation, certain actions and situations are deemed outside the scope of coverage. When an employee is violating a company rule during their lunch break, this situation typically falls outside the protective umbrella of workers' compensation. The rationale is that employees are expected to follow company policies at all times, and when they choose to disregard those policies, they may be engaging in behavior that is not covered under workers' compensation laws.

Workers' compensation is designed to cover injuries that occur in the course of employment as long as the employee is performing job-related duties or is in a work-related environment. However, if an employee is on a lunch break and engaging in activities that violate company rules, they may no longer be considered to be acting within the scope of their employment. This delineation helps maintain accountability for both employees and employers regarding workplace standards and safety.

In this case, options such as the known risk of injury, injuries caused by a coworker’s carelessness, and contributory negligence can still be part of a workers' compensation claim under specific circumstances. These factors generally address workplace safety and employer liability, which differ from the implications of violating company rules.
