I put up with unacceptable behavior from someone over whom I had (limited) authority recently, and I think what upset me more than anything was that I wound up apologizing for setting him off, when I had done nothing wrong. I have a very hard time standing up for myself dealing with people like that. Fortunately, he was 2 weeks from retirement at the time, so I knew I wouldn't have to deal with him much longer.
I have some leftover crap from my last assignment--certain people with authority over me don't like me, so I'm always wary that any rocking of the boat will wind up tipping me into the soup.
I hope you will do better than I did, though, and stand up for yourself and the others in your workplace by stopping the bully before it gets worse.
Hugs, I wish I could be more inspiring. I think this time YOU will have to inspire ME.
