After years of quality hard work, you, the star employee, have been promoted to be a manager of a team, a first-time accomplishment for you. Congrats! You should take time to feel proud of this achievement. But you also dont have time to waste.

As soon as you accept this new role, your superiors and your reports will be judging how you lead, and once opinions are formed, they will be hard to shake off. You have to prove yourself all over again. And what worked for you as an individual performer may be your downfall as a manager of warring egos and goals.
