No one gets more annoyed than when a leader does not have good time management skills. For example, the leader might spring projects on subordinates at the last minute. This encourages resentment. Leaders who keep things running smoothly and manage busy periods well are rewarded with happy subordinates.
Another aspect of time management is making sure that everything in a production process is being done as quickly as possible. Leaders need to analyze the production process in their firms to be sure that no time is being wasted through inefficient set up or organization.
Time management is extremely important in a leadership role. The person in a leadership role, like a manager, is often responsible for delegating the work to employees. It is very important that this person be able to manage the projects and the time it takes to complete them. A person in a leadership role must be able to keep up with deadlines and such independently. They must also be able to help others keep up with their deadliness and responsibilities. A leader has to be able to delegate appropriately. If I'm a leader and I know Johnny is going to take two weeks to do a project, I better assign it to him with plenty of time to complete the project before the deadline.
