I've been working with a coworker for about 6 months now and we have always had an awkward relationship. When I first worked there, whenever I asked a question she answered with an attitude like she thought I was dumb. (this is my first baking job) I caught her several times making an eye roll face. When we are alone working we rarely talk. I notice that she never asked me questions like how was your week or weekend. The only times she has talked to me jokingly was when there was another coworker there. For months I chalked it up to perhaps she's not a morning person. I thought that the longer we worked together our relationship would get better but it hasn't, if anything it has gotten worse. Worse enough that one morning she was mad that I didn't make a certain pie in the morning and a few hours later when our boss walked in she could feel the tension between us and asked what was wrong but we both didn't say anything. When my coworker was outside, my boss came to me and asked if something happened between her and I and I said no there was nothing. I would like to work there at least a year so I don't want quit yet but I'm just struggling to be cheerful in the workplace when my coworker's snappy attitude puts in not so great mood. I mentioned my problem with another coworker because she was going to leave soon and she told me that she has a problem with everyone. Another coworker told me that she was in a better mood one week and in my head I was thinking, that's the week I asked off.
Do you think I should mention something to my boss? I don't want her to get fired because I know she's a single parent and she's a great asset to the team and a hard worker, we just don't mesh together well.
