I had a boss like that like, he was so insecure it was unreal. I was the only one out of six of us who used to stand up to him, so they always asked me to put things forward to him.
He tried to issue me a written warning for taking extra days off for my Dads funeral, even when I had phoned him and told him the situation, "problems with cemetery" which was OK with him then?
When I came back, I had a right row with him, then stormed out, and went to see the manager, who was surprised to see me, as he thought I was still in leave?
The manager, who was a sensible bloke, and told me he knew of the situation about my bosses insecurity
He then had "a word" with my boss, and after that he never bothered me much, but did go out if his way to make things harder for me, but I was used to that anyway.
