I worked for a manager who was firmly in the Bully school of doing things and I loathed working for him, he didn't like me. I did stand up to him and gave him no good reason to get rid of me. I ended up still being there when the entire project folded, mainly through his doing. I then walked into another job. I found out that several months later HE was still looking for a new post.

Be strong, and if the dickhead does fire you on such meagre grounds drag him into the courtroom, it won't look good on HIS appraisal.
