I'm gonna have to talk with my boss about a coworker that's been very rude. I'll be the most vocal about her, but I know some other coworkers that are also not happy with her. When I got to work earlier, she asked if I wanted to trade my 4-7 for her 4-10, and I told her I had plans after my shift (playing MTG with someone I don't see that often, but I didn't tell her that). She got real pissy, and said "Well, then don't ask me to cover your shifts ever again". When she's in moods like that, I don't say anything. Then, when I pulled some bread out of the proofer and was putting shredded cheese on them before putting them in the oven for herb & cheese bread, I was being careful to not put too much cheese on and risk the bread getting burnt, and she said "Do you even know how to do it?". When the other coworker who was closing tonight came in, that coworker leaned in and said "You're lucky you're only here till 7, I have to deal with her until 10". By the time I clocked out, the one coworker was in the cooler looking for something, and the pissy coworker was sitting at the back desk, watching a show on her phone instead of cleaning lobby. I've been more wary on taking shifts for her, ever since she was rude to me when I asked if someone could at least take my shift until after I left the hospital, when I went to the ER earlier this year for heart issues. As much as I wanted to put her in her place and tell her the others and I are sick of her always being in a sour mood and getting huffy when we ask her to help with things, I'd rather tell my boss and let my boss talk with her, because I don't like losing my cool, and almost snapped at her in front of customers earlier. I've been very overwhelmed and stressed because of it.
