I read an interesting article in the Associated Press regarding a Pennsylvania Appellate Court holding that police officers who lose their sense of smell might also risk losing their jobs.
The Pennsylvania Commonwealth Court ruled that a suburban Pittsburgh township had the right to terminate one of its police officers after he lost his sense of smell in an off duty motorcycle accident. The reasoning for the termination was because police officers must be able to detect drugs, alcohol, hazardous materials, natural gas and other substances.
Obviously, if the loss of smell was related to a work related injury then the officer could still be fired, but his workers' compensation weekly wage benefits would have to be paid. Unfortunately for this officer, the accident was not work related.
