Hump Day Humor - Example of the Peter Principle

The Peter Principle is the principle that "In a Hierarchy Every Employee Tends to Rise to His Level of Incompetence." While formulated by Dr. Laurence J. Peter and Raymond Hull in their 1968 book The Peter Principle, a humorous treatise which also introduced the "salutary science of Hierarchiology", "inadvertently founded" by Peter, the principle has real validity. It holds that in a hierarchy, members are promoted so long as they work competently. Sooner or later they are promoted to a position at which they are no longer competent (their "level of incompetence"), and there they remain. Peter's Corollary states that "in time, every post tends to be occupied by an employee who is incompetent to carry out his duties" and adds that "work is accomplished by those employees who have not yet reached their level of incompetence".
