Respect, expectations, pay, growth. Miss one, and you're already training their replacement. The Dynamos break down why people really leave and why "I know my job" is the most expensive sentence in your office. "I know my job, I don't need that." Spoiler: nothing crashes because people didn't know how to do the work. It crashes because everyone assumed somebody else had it covered.

If you're rehiring the same position every eight months, this one's for you.
