I am resigning from my job at a small company that I've been at for only about four months. I am quite young and have spent the two years prior to this job dealing with health issues, so this job will be the most prominent on future resumes.
I am leaving my job because my employer's short temper makes me very uncomfortable, and he often belittles and puts me down. More concerning though, he has been having financial issues, and for the past two months would not pay me or even give me any notice of when he could. He only finally paid me in-full recently.
I am hesitant to ask my boss for a reference as things feel tense at work. Will not having a reference potentially hurt my future career chances, despite not wanting to return to my current field of work?
