What is the test for a claim for psychological injury resulting from workplace harassment after a compensable injury?

The 2000 case, Harry v. WCB, deals with a claim for a psychological injury resulting from workplace harassment after a compensable injury. That worker’s claim was denied as the policy, as it existed at that time (issued on February 15, 1997), only permitted a claim for physiological disability if the condition resulted from an emotional reaction to a single traumatic work-related incident. As the worker in that case had been harassed over a period of time, and was not able to demonstrate a single traumatic event, his claim was denied.
