My friend works in a factory manufacturing car parts. This guy started working there and has basically been creepy and harassing a few female employees and at least two male employees. He's a blowhard who is always talking about his friendship with the GM and “their time in the Marines.” My friend looked him up and found out he had served time for burglary, assault and identity theft. She linked the details of the case and he actually forced his way into his ex girlfriends apartment, held his ex girlfriend at gun point, said he wanted her back, prevented her from leaving and going to work for 2 days- attempted to tie her up (she talked him out of it) and eventually stole her wallet and bought airline tickets to another country. (He was caught before that flight). Their group leader was sent a copy of this and he supposedly sent it to HR. But she has had a terrible time with their HR before, and the group leader has ALWAYS let everything slide with this guy. The harassment had not been physical YET, but not along the lines of him trying to get ladies to go out with him, being openly sexist; and just sophomoric shit, like blocking them from backing up in the parking lot, honking at them, etc. What should she do?
