I work in a restaurant and one co-worker in particular is known to harass and be aggressive to many of my other co-worker's yet my GM or DM refuse to do anything in regards to his behaviour, he's an older gentleman probably about 70 and he doesn't do his job in the slightest, if he does have to do his job it's not without plenty of insults to everyone. He has gotten physical with my friend by throwing dishes at him because there was a bit of cheese on the cheese pan despite him wanting to be on dishes, he will leave his station to come harass me and say I'm not doing my job right but gets aggressive when I say “no manager is saying I'm doing my job incorrectly.” While we're trying to close he will sit in the lobby saying he wants to go home and doesn't help in the slightest, it's becoming so stressful I feel like quitting just to avoid his tantrums should I go to HR about this or should I just wait until he eventually gets fired?
