Learn to Delegate

Managers often dump unrealistic workloads on their employees and hand over tasks that people aren't equipped to handle. They give over the work without empowering employees to handle it, and then they blame employees when it doesn't work out.

Solution: Learn to delegate properly. The reason for delegating work is to lighten the manager's workload and also to educate/train those under him/her to help them grow. Work delegated always should be appropriate to the ability of the employee to whom it's given. If the manager has authority to do X with a project, if that project is delegated, the person receiving it must also have the authority to do X in order to accomplish the task. The employee must be given the training and tools to do any job properly.
