I’m new to my office (around a month) and an offer of overtime came up today. I immediately said yes because money is tight and I could do with it. After I said yes, I was pulled to the side and said that even though it’s offered to the whole office, there’s usually three part time workers who take it because they’re always struggling. Apparently it’s a bit of an unwritten rule. AIBU to take it anyway? Even if it’s just for a month or two I could really use the money heading into the new year
