My supervisor is on vacation next week. So I’m wondering if it will be a good time to mention it to a manager.

Yes I went in sick but the day before a coworker was sick and he was asking her if she was ok and if she needed the fan on or if she wanted to borrow his jacket. She left early and he was all like “feel better” yet when I left I was a “dumbass” I just don’t think it’s very fair treatment.
