To be able to lead, managers need authority that corresponds to leadership responsibility. Accept responsibility for your area. Demand the necessary decision-making authority from your supervisor. Prevent your superiors from “overruling” and thereby taking away your leadership authority in your area. Make sure that the necessary conditions for performance are created in your area of responsibility. Demand responsibility for your cost center. Ensure that you are involved in budget preparation for your area of responsibility. Agree on goals for your area of responsibility with your supervisor. Demand at least a veto right for personnel decisions in your area of responsibility.
When you lead, you lead. This also requires a role model function.
