So, I work part time & part of my role is as supervisor to a small 'team'. One of them is a bitch to me & it's all I can think about on my day off when i should be food shopping & spending time with DC. I'm worried about what i'll miss at work which will be used as power against me. She works full time & therefore spends more time at work & in some respects knows what's going on day to day, whereas being part time I need to catch up with what happened yesterday etc. She started off making snidey remarks about me to others 'what's the difference in her role & mine' 'she's never here'. So I ignored all that & she's upped the ante: 'why don't you give us more support?' 'I can't believe you let the customer talk to you like that' and lots more of the same to the point that when she's around I can feel myself shaking. She takes great delight in this by being even louder & brashier & announcing every great thing she has done/ is doing. It's getting me down
