At one of Henry Ford’s factories, a brigade of workers received money for resting. It was a service brigade that was responsible for the uninterrupted operation of the conveyor. In other words, the repairers. They were only paid when they were sitting in the rest room. As soon as the red lamp of the breakdown of the assembly line was lit, the counter stopped, charging them money.
First, they always made repairs promptly to return to the rest room faster. Secondly, they made repairs always qualitatively so that they did not have to leave the room soon due to the same malfunction.
