Getting a new boss can be nerve-wracking. For better or worse, you've figured out how to work with the current manager. You know how long it takes him or her to reply to an email, the best approach for pitching new ideas, and how he or she defines "Urgent!"

But there's no denying that working for someone new is an opportunity. Even if you're one of the lucky few who loves your boss, a new person will push you to grow. At the very least, building that rapport all over again is a valuable skill.
