The falsification practices that are being discussed are very widespread. If you took the time, and had the desire, you'd find it in your own station. All you'd have to do was follow someone with astounding numbers during their 13/14 "lunch hour". Maybe your station goes by the book, but I doubt it.
That doesn't mean that FedEx encourages it, it just means that there are managers allow it. Personally, if/when I notice it, it's addressed immediately.....i'm not going to get fired for looking the other way b/c one of my employees chooses to falsify.
