I have recently started a new job. One of my colleagues is pretty much making my life a misery. She's extremely rude, passive aggressive and rather nasty.
She works part time, and I actually dread going in on her shift days. If I need appointments or meetings I aim to arrange them for when she is working to minimise time I need to spend with her.
I am not the only person she behaves like this with, another colleague who is very lovely confided in me that I'm not the only one. (They could see I was upset, and asked about it. They mentioned that nasty colleague was the same when they first started, and another colleague mentioned to them about nasty colleague literally a couple of weeks ago).
Nice colleague advised the way to deal with nasty colleague is to defer to her, and not question or challenge anything she says/does. Whilst I accept this would potentially make for a nicer working environment due to less conflict, it doesnt feel right to just defer constantly or risk being basically bullied until you do.
Does anyone have any tips as to how to deal with this? I've already mentioned the issues to my line manager.
