Mary Parker Follet said it best “Unity, not uniformity, must be our aim. We attain unity only through variety. Differences must be integrated, not annihilated, not absorbed.”
Most people care to do a good at whatever it is they are doing. In almost all situations, I remember this fundamental rule. Everything else can be worked out. People progress differently and it is more difficult for some managers to be flexible rather than rigid. There are going to be tough situations that require leadership and unless there is someone remembering this rule, the situation will not be resolved in a constructive way.
There comes a point during the management progression where you realize that it is most effective to guide others rather than become controlling. I have learned that you cannot make anyone do anything, so what is most important is the approach to the situation to influence others to take the right course of action.
