Last week my manager at work asked me if I could swap my Wednesday shift, for the guy who does Saturdays because he's away on holiday, I agree to this no bother.
Got a phonecall on Wednesday asking where I was, and why I wasn't in work. Told them about the shift swap, to be told that was actually next week and I was due to be in, which I couldn't make due to the uni work I had to be handed in on the Thursday, so I was definitely in on the Wednesday and not the Saturday.
Got a phonecall today asking why I wasn't in work, despite the fact the rota clearly says I'm off today.
I fucking hate my work.
