Many times that I knew some sort of stuff like this happened, it was because one specific worker, KNEW that he was doing wrong, but did it wrong anyway to take the credit, and hope his bosses would not find out.
This also apply when the "worker" is a boss, but working for a client, he do it in a lazy manner hoping his client won't notice...
