A good manager need to know how to motivate their employees and deal with other people

A good manager motivates their employees to strive and achieve

A good manager keeps his or her employees motivated and this can be accomplished through the magic of encouragement. A person rewarded for their work and contributions, similar to a trained animal, will be motivated and encouraged to repeat this same behaviour and internalize it into their systems. Everybody likes the positive reinforcement that encouragement brings to us.

You have to be comfortable dealing with people

As a manager, people form your greatest resource and your main task is to utilize your resources to skilfully accomplish the shared task. As such, you have to be comfortable when dealing with people.
Part of a manager’s role is the delegation of tasks. A good manager has to be skilled as well as comfortable in the delegation of tasks. He has to empathically feel out the situation and carefully analyse potential outcomes before making the correct task allocations.

Some tips on how to delegate more comfortably without arousing any resentment will be to perhaps ask questions before giving direct orders. This will make the task appear to be the employee’s idea, and will result in the employee being more accommodating and perhaps even enthusiastic to perform to the task assigned.
