The proof of the sincerity and seriousness of a management is uncompromising emphasis on integrity of character.

The proof of the sincerity and seriousness of a management is uncompromising emphasis on integrity of character. This, above all, has to be symbolized in management’s “people” decisions. For it is character through which leadership is exercised; it is character that sets the example and is imitated. Character is not something one can fool people about. The people with whom a person works, and especially subordinates, know in a few weeks whether he or she has integrity or not. They may forgive a person for a great deal: incompetence, ignorance, insecurity, or bad manners. But they will not forgive a lack of integrity in that person. Nor will they forgive higher management for choosing him.

This is particularly true of the people at the head of an enterprise. For the spirit of an organization is created from the top. If an organization is great in spirit, it is because the spirit of its top people is great. If it decays, it does so because the top rots; as the proverb has it, “Trees die from the top.” No one should ever be appointed to a senior position unless top management is willing to have his or her character serve as the model for subordinates.
