Though your job as manager may be new to you, having a manager is not new to the people who report to you. You're stepping in to replace someone else. Employees may be relieved and happy to see you in your position, or they may be disgruntled and unhappy that the previous manager is gone. Did you come up through the ranks, or are you new to the company? The circumstances of how you got to be manager greatly influence how successful you will be in your new role.
