The biggest and most obvious thing is his PTSD. He does deal with a lot of nonsense but he also doesn’t realise the way he handles things doesn’t help. He’s so highly strung these days he can’t just let little things go or play the political game in order to solve an issue. He’s a hammer and everything looks like a nail.
The job gave him PTSD so I don’t think there’s a way he could stay in it and have the treatment be successful. But he’s in no shape to go on a job hunt right now either. I just hope he can make it to stress leave.
