Long time poster, username changed to protect the (not so) innocent.
I work with two other people - A and B. A works three days, B works two days, I work two days. So say A works M-W, B works M-T and I work W-Th. We're all on the same level, same pay, same job. A has the same amount (maybe a little less) experience than I have, B has a lot (a decade or so) more than us.
B isn't the problem, it's A. A constantly comments on what I do, it's like a never-ending flow of criticism. It doesn't matter what I do, it's wrong.
Examples - in the time I've worked there we've always done something a certain way, I'll do it one day and it's changed. No one told me, I'm supposed to just guess a procedure has changed. A is exasperated that I've done it wrong, how could I not know?! It's not a big deal, I know now, no lives where lost. Let's move on. But no, from that day forth, she mentions it. Remember we do X now, not Y! Yes, thank you, I know. Times this by every part of my job. Even stupid things like leaving water in the kettle - we've always left water in the kettle to prevent anyone dry boiling it and we empty it every night. Oh no, now we must empty it every time. "Look, could you PLEASE empty the kettle after you use it, there is no need to leave water in it."
and so on, the pen I'm using, the way I've filed this, the way I've opened a window. On and on and on.
She also likes to "joke" that I'm lazy. If I go off to do a task out of sight, she comments loudly that I should be "doing my job" rather that lounging around, hahaha
One time she was asked to do something, a quick task but she was in the middle of something, so I offered to do it. She turned around and scowled at me, "allow me to do my job, please." But she has no problems doing things I've been specifically asked to do. It makes no difference who does them as long as they're done.
A would never talk to B how she talks to me. If B is around A is fine, it's just on the day I'm alone with her that she lets it rip. B is lovely and doesn't have any problems with how I do my job. My boss is happy with me, everyone I work with doesn't have a problem - I've asked! They've even commented on how A treats me. Unfortunately moving away from working with A isn't possible.
So, MN hive mind. I need some come backs. I'm dreading going into work on Tuesday. I need something in my back pocket to reply with to get her to understand I'm capable of doing my job and she needn't continue critiquing everything I do. I'm terrible with conflict and up until now I've just nodded and smiled but I need it to stop. Help.
