Hi, i just need some advice on how i can handle this. A coworker (a) has been telling coworker (b) that he plans on offering me narcotic painkillers then reporting me for "stealing" them. Then plans to have me drug tested and fired. I have never stolen ANYTHING from him. He simply just doesn't like me. I also have never failed a UA. Coworker B says that he'll come forth and tell someone that coworker A has been planning this, but only if it happens. Obviously I wouldn't take them anyway. Ive told my boss, but he says he can't do anything because nothing has happened. Is there anything I can do or say to someone that will actually make a difference?
