Check out my article at workforce.com on Good vs. Bad Turnover...
Here's how it starts:
"I know what you are thinking about turnover. As a practical HR pro, you already know that all turnover is not created equal.

(A new record! Unfortunately, none of them were quite enough for you to discipline or terminate him.) Jim was good turnover—really good turnover."
