He got a verbal warning last week for losing something at work. Yesterday his manager accused him of not doing his job yesterday and said he needed to sort himself out. He argued a bit with her then left it be. Now, he doesn't live with me but we are considering it. I don't think he's in the right position to be arguing with his manager right now and should have tackled it differently. AIBU to think he needs to come down a peg, apologise today, explain himself and agree to put it behind him and make today a fresh day?
