I've name changed for this but here goes.
For the last 3 weeks I've been doing something at work that hasn't impacted anyone at all and nobody has noticed...until Monday. On Monday a senior manager discovered what I'd been doing and was angry and asked my supervisor to have a word with me. The supervisor had a word and told me not to do it again. I apologised and said I wouldn't even though I don't really have an option but to continue doing it.
However, the very next day (Tuesday, yesterday) I did it again. I didn't expect anyone to notice, as like I said, I've been doing this thing for 3 weeks and nobody's noticed. Well, obviously someone was keeping an eye on me because I got caught and this time I got a proper telling off and a 'record of discussion' is now going on my file.
Now, my AIBU is, I really don't have much choice but to continue doing the thing, at least for the time being, so would it be really that bad to do it again on my next shift which is the weekend, where there will be skeleton staff who won't know I've already been in trouble?
Just to add, many staff members are doing a very, very, similar thing openly but slightly differently which I feel is unfair. And, to clarify, it's not office based; we are an establishment that is supposed to be all about supporting 'the thing' I'm doing.
