I don't agree. I think you should catch this motherfucker outside of work and work him over with a pipe. you'll be surprised what an adjustment of attitude that can cause. and trust me, he won't turn you in b/c he'll be too scared that you might do something even crazier (like come after his family). after all, who can tell what someone who would beat you with a pipe after work will do?
