At one of the factories of Henry Ford, a team of workers received money for resting. This was the service team responsible for the smooth operation of the conveyor. Simply put, they are repairmen. They only got paid when they were in the break room. As soon as the red lamp of the breakdown of the assembly line came on, the counter stopped, charging them money.
Firstly, they always quickly made repairs in order to quickly return to the rest room. Secondly, they always made high quality repairs so that they did not have to leave the room in the near future due to the same malfunction.
