I have to work closely with a colleague who is, quite frankly, a nasty, spiteful person. She thinks she owns the office and always tries to tell us all what to do, whilst saying stuff about us all behind our backs. I've just been told today about some really horrible stuff she's said about me.
Management know what she's like but dismiss it as 'she's just like that' and because she's been there for a long time they won't do a thing about it. She's totally shit at the job, too, but picks fault in the rest of us and how we do things.
I was thinking of just not speaking to her the next time I have to work with her and just answering her in a cold, politeish way but not engaging with her in any other capacity. She's all nice to our faces.
I need to do something as my mental health will suffer otherwise
