Damnit, I'm upset. There's someone I work with who I don't get on with and she's decided to make a formal complaint against me for my behaviour towards her.

This woman is an unpleasant bully who's made my life miserable for several months and the single time I've lost my temper with her and got annoyed back, she's complained.

Luckily

a) My manager's told me he thinks it's a personality clash and not to worry too much though they have to investigate.

b) I have a copy of an email exchange immediately after the incident I think she's complaining about where I apologise for snapping and also ask her not to be so confrontational and aggressive in the future. Plus her reply whcih accues me of pretty much the same but also acknowledges that she has come across as aggressive and confrontational. So I think I should be okay.

But nonetheless I'm really upset about the situation.

Has anyone else had formal complaints made against them? What happens?
