To encourage competition, managers publicly post a ranking of employee productivity at the end of each day. In some warehouses, there’s a whiteboard; in others, a printed piece of paper or an electronic display. Ashleigh Strange, who worked at a warehouse in Breinigsville, Pennsylvania between 2013 and 2015, said this practice was also a “method of group shaming.” “If you were the worst person in the warehouse,” Ashleigh said, “you’re going to know it. And so will everyone else.” In some warehouses, bottom performers are automatically enrolled in remedial training — or written up.

Management also runs what employees called “power hours,” during which workers are incentivized by raffle tickets or Amazon “swag” to work as fast as humanly possible. “You get an unimportant reward for working as fast as you can,” said Charlie. “Everyone competes. This becomes the new baseline.”

Online Amazon worker forums are full of strategies for artificially boosting rates. One worker discovered that managers were basing his productivity numbers on how quickly he started work after a break. By leaving a count loaded in his scanner, he could trick the computer into thinking he had resumed work with a flurry of activity. Others boost their count by rapidly scanning several bins of small items.
