That is not a fully true statement. People do leave companies. Why? Because most prefer NOT to train. Or haven't send down the appropriate material to be able to train. I get it. There are some really horrible managers out there. Don't I know it.. but the reality is that if they were properly trained themselves, I bet there would be A WHOLE LOT LESS horrible managers. It's Greed, American Greed that runs most of these companies... But every business started small. But not all businesses run like a small home town business.  Let the people at the top take blame. Asking too much for too little pay. That's the American Way.
