I'm quitting my job soon. I liked the day-to-day tasks my role entailed. I didn't like the people (most of them), lack of boundaries, sexual perversion, or blatant disregard management had for our safety. I'm going to grad school so I MAY need this employer as a rec for the future. I'm not sure yet.
Should I be honest? Or I guess, how honest should I be about my feedback?
