There is a saying out there that has a lot of truth to it: You are only as good as your last manager.
Not that the manager is the difference in your capabilities, your skills, or your talents. Those things don’t change much.
But a good manager, at worst, will do your career no harm. A great manager will push you in all the right ways to improve yourself and your personal brand.
A bad manager is simply bad for you, your career and your personal brand.

How many others do you see in your work?
Get a few bad managers in a row and it can really set back your career. Do you have a bad manager? If you do, you have a quick choice: outlast the one manager and hope the next one is better. Or, get two bad managers in a row and figure out how to get out of the department — or Company.
