After working six months at Amazon, he was told, without warning or explanation, that his target rates for packages had doubled from 250 units per hour to 500.
Zweifel was able to make the pace, but he saw older workers who could not and were getting written up a lot and most of whom were fired. A temporary employee at the same warehouse, in his fifties, worked ten hours a day as a picker, taking items from bins and delivering them to the shelves. He would walk thirteen to fifteen miles daily. He was told he had to pick 1,200 items in a ten-hour shift, or 1 item every thirty seconds. He had to get down on his hands and knees 250 to 300 times a day to do this. He got written up for not working fast enough, and when he was fired only three of the one hundred temporary workers hired with him had survived.
