((cromsworld)),
That really sounds like a very challenging scenario, it's not good that others are feeling intimidated by this man. It sounds like he is a bully at work, pushing himself at people. I can see why you are concerned. Do you have anyone you can talk to at work about this problem?

I understand what others here are saying, try to respect that this man is struggling and has PTSD and is a Veteran. But, I would not want to see something bad happen, and people not say anything because they are
trying to respect that he has problems.
