The Peter Principle (1969) is a book by Laurence J. Peter & Raymond Hull on career & skills.

Why it’s on the shelf

A single mischievous law explains almost every incompetent boss you've ever had: people rise until the job they're good at promotes them into one they aren't.

Two of the ideas you’ll keep

The Clif summary of The Peter Principle pulls out 7 insights. Here are the first two.

  1. The Peter Principle: 'In a hierarchy every employee tends to rise to his level of incompetence.' Competence earns promotion; promotion continues until you land in a job you can't do well, and there you remain.
  2. Its corollary is the book's darkest joke: given enough time, every post in a hierarchy tends to be occupied by someone incompetent to carry out its duties, so the actual work gets done by employees who haven't yet reached their level of incompetence.
