I work in a large team, there are 4 of us who have the same role as me.
One of my same role colleagues I really don't get on with, a lot of the wider team also find her difficult. She has a very large sense of superiority, likes to tell people what to do, is very backstabbing (is mates with the managers so tells them everything she hears) and lots of other things that become quite outing to describe.
She doesn't like me (I can tell), mostly I think because I have come to the team relatively recently and she doesn't like that I don't kiss her ass and that I have made suggestions she doesn't like for the work. However, she does that sickly, pretending we're all mates crap to your face that is even worse by knowing it's all a load of BS.
I sometimes consider actually just saying to her that we both know we aren't friends and we don't like each other so why don't we just cut the crap and stop the fakeness - let's just get on with our jobs and that's all.
AIBU to do this? I literally don't care about what she would think of me because of it - I know she doesn't like me anyway. My boss knows we have a difficult relationship and is supportive of me having to deal with it and I guess I worry she will think I am being immature. I feel like it will make things easier and actually cause less stress!
