The courts have recognized that a certain amount of "horseplay" is to be expected on most jobs and that if a worker is injured as a result of such horseplay, that injury is compensable. The courts have also held, however, that there is a limit to this situation. If the worker is injured as a result of his or her "intentional and willful misconduct," he or she is not entitled to benefits. The courts have held that if an injury results from a violation of a rule which is clearly announced and regularly enforced by the employer, the worker is not entitled to workers' compensation benefits.
