Why do people leave their jobs? When I first read Marcus Buckingham’s First, Break All the Rules, I was flummoxed. The things that I had gut feel about could be proven with facts and concrete examples. People leave their jobs mainly because of their supervisors. Go get the book – you may not agree with all the ideas in there, but there’s enough thought in there to spark some interesting discussions and new awareness in the areas of satisfaction at the workplace, methinks.
