“The Peter Principle was laid out by Canadian educational scholar and sociologist, Dr. Laurence J. Peter, in his 1968 book titled ‘The Peter Principle.’
The Peter Principle is the logical idea that competent employees will continue to be promoted, but at some point will be promoted into positions for which they are incompetent, and they will then remain in those positions because of the fact that they do not demonstrate any further competence that would get them recognized for additional promotion. According to the Peter Principle, every position in a given hierarchy will eventually be filled by employees who are incompetent to fulfill the job duties of their respective positions.
Dr. Peter further argued that employees tend to remain in positions for which they are incompetent because mere incompetence is rarely sufficient to cause the employee to be fired from the position. Ordinarily, only extreme incompetence causes dismissal.“
