<prompt> Human: Im almost certain Im posting this in the wrong place but so many of you seem to have expert advice for these kinds of situations. So here we go. My boss is a hugely unpleasant guy, an opinion shared by every single one of my colleagues. About 2 months ago I had to call in due to sickness for my 1st shift back after a 4 day break. The very next time my boss laid eyes on me he immediately started making sarcastic comments about me having an extended holiday and implying that I was straight up lying. Then on the 1st of this month I had my progress update which happens twice a year, and again he berated me for calling in sick that time. The very next Day My day off I come down with the worst fever Ive ever had. Without sounding overly dramatic, it was the most unpleasant thing Ive ever experienced. I called in for my shift on Sat 3rd and told him I wont be coming in, to which he angrily said ok and hung up. Now were at Sunday and Im still not feeling anywhere near ready to work Let me add that I work in a very physically demanding job that is also customer-facing. I want to call in but in my progress update I was flat out told that should things not improve, I will receive a disciplinary. What do I do?  <response>: Go in, vomit on him, checkmate.
