An employer fired a commissionaire for his conduct, including failing to obey directions and refusing assignments. The commissionaire claimed that he’d been fired for raising health and safety concerns, including exposure to smoke and hepatitis at a halfway house and exposure to high levels of dust at an airport hanger. The OHS Appeal Panel dismissed his complaint, ruling that the employer had valid business reasons for his termination. His concerns about exposure to smoke and dust may have been legitimate but he never notified his employer about them or followed work refusal procedures. Instead, he just complained to co-workers. In addition, there was no medical evidence that his health had been affected by exposure to the dust [O.H.S. No. OHS-00131,  NSOHSAP 21 (CanLII), Feb. 10, 2011].
