This question already has an answer here:
I am currently working for a small company that is not going to survive due to mismanagement. The director of the company is chaotic, verbally abusive, and generally pretty bad at making any sort of sensible decision for the future of the company or its employees, and changes his mind about significant projects several times a week.
Because of this, 80% of my colleagues are actively looking for another job with quite some urgency. I know this because it is openly discussed among the staff when the director is not in the office (frequently).
In a previous position I dealt with misbehaving managers by actively tackling the issue in discussion with them and their bosses, but in that case I had a large corporate structure to back me up.
As a result of all of this, I am underutilized, bored and frankly wasting my time, but I have only worked with the company for less than 6 months.
My question then:
How should I explain why I left my last job in an interview without looking like a badmouth - or a coward - and how do I approach this on my CV?
This question is related to How should I explain that I'm looking for a job because my employer may be shutting down? but is focussed on my next employer.
