I recently worked at a small pub for two months as front of house staff. Unfortunately, my experience was marred by harassment from one of the bartenders/servers, which escalated despite my manager's attempts to address it. I ultimately decided to put in my two weeks' notice due to the ongoing issues. My manager, who is also the owner, has offered to give me a good reference for future job applications, but I'm conflicted about using him. This was my first job after a few years off, so I don't have many references to draw from. I'm concerned about how my short tenure at the pub will be perceived by potential employers. Should I use my manager as a reference despite the circumstances, or would it be better to say I don't have any current references?
