I have been working at an Insurance company's IT department for about 3 months now as an IT Project Manager. I really love the company I work for, no matter the "growing pains"; however, I have become privy to some really sensitive issues.
In particular there is a manager who I found out was having an affair with her supervisor (our VP). I only know this because she sent me vulgar/sexual messages via Lync and then quickly called me into her office and demanded that I never tell anyone. With this relationship she is able to influence decisions & directions and feed him information about people she doesn't like - we have had 5 people let go already in the few months I have been here. Maybe there isn't a cause and effect there, but it does not give me a warm and fuzzy feeling.
How can I explain my reasons for leaving to my potential employers without telling them precisely? I know it is none of their business, but I don't want to lie and say the company is total crap when that is far from the truth. I want to just say it is an ethical issue, even though it is a little more than that, but I really do not want to get into detail.
What is the best way to explain this reasoning?
