High turnover, kind of a sweat shop, forced ranking often moves people at the top years before to out the bottom a few years later even though no chnage in performance, especially in high performing teams. As a manager, if you do a superior job recruiting high caliber team members, you are eventually penalized by having to force rank strong performers to below average to satisfy "the Curve". Also, when problems occurr, the tendency is to blame people, not systems or policies. Employees feel insecuree about continued employment.
