Betrayal of friendship. Short story, had a friend of 15 years working for me accuse me of harassment and creating a hostile work environment (legal terminology), then added sexual harassment (we are both male) , when he did not get a titled position and instead got the "you need to be more productive" talk and a salary realignment (not my decision but I had to be the bearer of the bad news). 6 month of legal and human resources investigations (during which time my lawyer will not allow me to talk to him alone-----tough to be an effective boss) and I am fully vindicated and he is un employed are not my idea of a good use of time and effort. Tough to imagine any kind of future friendship after that.
