Pit manager

A pit boss (more commonly known today as the pit manager) is the person who looks after the employees who work in a casino pit. The job of the pit boss is to watch the floormen, who are the supervisors for table games dealers in a casino. One pit boss monitors all floormen in the pit; there is usually one floorman for every three dealers. The floormen correct minor mistakes but if a serious gaming discrepancy arises (such as duplicate cards being found in a deck), it is the job of the pit boss to sort it out.
