In my ~13 years of experience, I've never worked under a manager who enabled or trusted me. I've always left a job because of new management, a policy instituted by a manager, or because the manager made me work on holidays, or being available to clients on my vacation. Generally, it's the 'shit on the employee in the name of the client' that pisses me off.

I'm of the opinion now that managers are a waste of resources and amount to baby-sitters who attend meetings, approve time off, and try to get me to work more.

I haven't met a manager yet who made a positive contribution to a project. There's a reason people shit on them!
