Generally speaking, the PA workers’ compensation system is a “no fault” system. It usually doesn’t matter why an employee gets hurt, as long as he or she was doing his or her job at the time. As with most rules, of course, there are exceptions. One exception to this rule is when a work injury is suffered through the violation of a positive work order.
One common thread in cases which discuss the “violation of a positive work order” defense is an incredibly stupid action on the part of an injured worker. A recent decision by the Commonwealth Court of Pennsylvania, in Habib v. Workers’ Compensation Appeal Board (John Roth Paving Pavemasters), did not deviate far from this thread.
In this case, the employee, a laborer, was awaiting a delivery of asphalt. To pass the time, he elected to see if he could break a bowling ball with a sledgehammer. The employee struck the bowling ball once, and it cracked. The foreman then told him to “knock it off.” Undaunted, the employee smashed the ball again, causing a piece of the ball to strike the employee in the eye (leading to a loss of his eye).
