The members of each Chain Gang are hired locally by the home team. There is no set standard salary, but the pay appears to be about $40 to $50 per game. Some teams will give the crew members a ticket to the game for their spouse or a friend.
There are typically 7 to 8 members of the crew and they work directly with the head linesman marking first downs and the line of scrimmage. Although they work with the linesman, the chain gang members are not official NFL referees.
Chain crew assignments include:
Sets and moves after instructed by the Linesman
Changes number on box after moving to new spot; set box on heel of Linesman
Spot box at 3 yard line on Points After Touchdown
Drop box when players come at you from the field of play
Never move unless instructed by the Linesman, who will motion with arm for them to move

Drop chains when players come at you from the field of play
