The latest scandal to emerge from Amazon’s warehouses centers on the company’s newly patented wristband, which gives it the ability to track and record employees’ hands in real time. Some have described the technology as a “dystopian” form of surveillance. Amazon has countered that journalists are engaging in “misguided” speculation. To hear the retail giant tell it, all the device does is move its inventory-tracking equipment from workers’ hands to their wrists — what’s the big deal?

Given the level of surveillance and regimentation already in place in Amazon warehouses, the company isn’t completely off base. Currently, warehouse workers called pickers carry a scanner that directs them from product to product. All shift they race the countdown clock, which shows them how many seconds they have to find the item, place it in their trolley, and scan the barcode.

A variation on this method exists in warehouses where robots bring the shelves to workers. There, workers stand in place as stacks of products present themselves one by one. For ten and a half hours, they must stoop and stretch to retrieve an item every nine seconds. The scanners control workers’ behavior by measuring it, preventing slowdowns and allowing managers to create new performance benchmarks. Quick workers raise the bar for everyone, while slow workers risk losing their job.
