All legally appointed leaders have the legal right to lead. Failure to obey a legal order is always grounds for punishment.
Most of the time it take more than this to be a good leader.
Great leaders...
Have a compelling vision that inspires followers.
Use the leadership style that works best given the situation.
Know intrinsic motivation is more powerful than extrinsic motivation and that poorly administered "carrots and sticks" often demotivate.
Create a positive organizational climate because creativity and other outcomes improve when a positive organizational climate makes it possible for followers to engage in the present.
Make sure followers know how to do what needs to be done.
Are assertive, confident and optimistic.
Foster loyalty with shared sacrifice and mutual support.
