People follow leaders regardless of rank, because of their personal qualities. Theorists distinguish between formal and informal leaders. Both are important. Both can abuse their position. Formal leaders lose their effectiveness when careerism takes over.
Informal leaders can be destructive when personal ambitions override organizational goals.
To view rank and position as responsibilities rather than privileges establishes a positive leadership climate for the future. Thou shalt be competent and confident enough to take a risk. There is no better way to stifle creativity or to dampen morale than to establish a leadership climate that will not tolerate mistakes. Leadership is risky business. Delegating responsibility and trusting people is risky business.
