The Peter Principle
I heard about this principle through friends who also recommended that I watch Office Space. The Peter Principle is promoting someone to the highest level of incompetence.
Years ago I was in a training class with a team from another department. The team members told me how they had hired in this one guy who was not that great of a worker and didn't get along with others so management decided to promote him up to get him out of there.
Go figure! Right?
