I have been overpaid at work, I thought the extra money was a back payment for a pay rise, but that is not the case and won't be on my pay slip until December.
I have spent most of the extra money, and had a chat with a colleague today about how nice it was to get that extra cash this month, and then realised that I was the only one who had it and I'd made a mistake thinking it was back paid pay rise.
I've been to see HR, they said it was their error and it would come off next months pay slip.
I'm going to really struggle next month, now- is there another way I could pay it back/ how can I word this? Thank you- it's about £400
