I just recently left my job due to what I felt was a poor manager.  When I came into the company, I believed very much in the idea that respect and trust should be given initially to a manager and that I had to earn that respect & trust from my superiors.  And within 6 months, I really think I did that and often got praise from executives and other managers in different departments (thus making my manager and the director of our IT dept look good). 

But another 6 months later, I started to lose respect and trust for my manager.  Without going into details, it progressively got worse and in the end I left because I could no longer respect this manager (I didn't really get more money when I left either FWIW).  So I agree with the assessment that trust & respect is the key to a good manager.  I often worked directly with the director of the department and because of the trust/respect we had developed, there wasn't a thing I wouldn't do for him and the likewise was true (he even offered to pay for certification classes).

Before I left, I spoke to the director quite candidly about this manager.  He knew my issues with that manager because of past situations that was brought to his attention by both myself and that manager.  But the one thing I did say was that manager needed to take some management classes.  He needed to learn not only how to manage a project but really to manage the people he has.  I doubt my suggestion will matter but I had to say it because I believed in the company and the director.  I also agree with whoever mentioned it but a review of management by their employees is also just as healthy as a yearly review by your manager.  It gives both sides some feedback for things to continue doing well, improve in areas and other concerns that need to be voiced.  If that company had that, I may still be there.
