He who excels in employing others humbles himself before them.

A good leader recognises the contributions of others, the value of their ideas and the contributions of their labour.
An atmosphere of mutual respect is the only environment in which effective communication is possible. One who rules through fear or authoritarian methods may find that his employees, subjects, etc. may hide or distort information he needs to act and decide effectively, through their fear of bearing bad news, or through resentment.
Respect given to subordinates by a boss does not imply informality or over-familiarity. An effective working relationship requires boss and employee to respect each other's person, but also the nature of the relationship and their roles within that relationship.
