This question already has an answer here:
I've decided to leave a start-up after a few months of employment because the boss has poor interpersonal skills, is disrespectful on a daily basis, and turns simple situations into stressful events.
When I was hired on it was just me and him, now there's an assistant. Would it be confrontational to admit that I'm leaving because of company culture? I want to be honest, but I'm afraid that may come across as a personal attack.
