They understand the only reason you need excessive rules and controls is if you think people are either evil or stupid. Management teaches that followers are there for the benefit of the bosses. Leaders understand their job is to serve others, not to be served. It's the leader's job to add value to others, to sell themselves and their vision. Leaders seek long-term vitality for their organization, not quick fixes.
Management focuses more on today and less on the future.
Leaders spend more time charting the course than charting results, more time problem predicting than problem solving. Management teaches that leaders should be distant and aloof from followers. Leaders understand that leadership is a relationship. Without that relationship there will be no trust or confidence and without trust and confidence there will be no risk and without risk there will be no change and without change organizations die. They lead from the front, not from the rear.
