Have started a new job which has turned out not to be anything like what I imagined or what was described to me at the interview. The culture there is to work through unpaid breaks, never to leave on time, also unpaid and to basically be highly stressed from the minute I arrive. I have been told im expected to arrive to start early (unpaid of course). I have a young baby and there is no way i can juggle everything not knowing exactly when i'll be home. For some reason I feel terrible about leaving so soon and am nervous and dreading telling them on Monday. It took a couple of months for the paperwork to be sorted and in that time they could have found somebody else. Has anyone else been in this position? AIBU to leave so soon, or am I being a bit pathetic worrying so much, should i just grow a pair and tell them straight? Any advice on how to approach this?
