My manager is leaving on Wednesday but today is officially her last day in the office. She has been here for years and isn't very popular and makes my life quite miserable tbh. Not bullying or anything serious but snidey and sarcastic. I bought her lunch yesterday at a restaurant and have brought in a box of chocs, champagne and a card to give her but my bf is saying i shouldn't bother with the bottle because she is awful, and that card and chocs will do. She is a nightmare to work for yet is totally oblivious. The problem is that I don't think anyone else has done anything for her because she isn't nice! Simple as that! WWYD? AIBU?
