Apologizing isn’t one of my strong suits!

Last Saturday right before I clocked out of a 12 hour shift my supervisor said I never clocked in. I said yes It’s on camera I clocked in right after he did.. and he made a big ole deal about it and raised His voice to me and my last words to him as I was walking out the door was oh shut the fuck up., the next day my manager wrote me up because I used vulgar language and I got a 3 day suspension, turns out I was on camera clocking in.. well I didn’t have to but I said sorry to my supervisor for what I said last week.. he walked right passed me and said yeah! .. guess who has sanitation duty all day? Lol
