An extensive report by the Daily Beast paints what one critic called a “worrying, distressing” picture of life for employees at Amazon’s hundreds of warehouses and fulfillment centers—detailing the high volume of 911 calls that come from the facilities and why workers are so frequently driven to desperation.

Between 2013 and 2018, emergency workers responded to at least 189 calls from Amazon warehouses across the country, Max Zahn and Sharif Paget reported. The calls detailed by the Daily Beast were not an exhaustive list, but applied to only about a quarter of Amazon’s U.S. facilities—46 warehouses in 17 states.

The calls detailed in the report mainly dealt with employees having mental health episodes including suicide attempts and expressing suicidal thoughts, with workers linking their episodes to the social isolation, surveillance, and break-neck pace of work they were subjected to at Amazon.

“It’s this isolating colony of hell where people having breakdowns is a regular occurrence,” Jace Crouch, a former employee who had worked in Lakeland, Florida, told the Daily Beast. Crouch said it had been “mentally taxing to do the same task super fast for 10-hour shifts, four or five days a week.”

On social media critics noted the juxtaposition between Amazon CEO Jeff Bezos’s status as the richest person in the world and his employees’ alleged experiences being aggressively monitored by managers and punished for taking bathroom breaks, while British Green Party politician Natalie Bennett wrote that the “tax-dodging Great Parasite” can now also be known as the “employer from hell.”

The trillion-dollar corporation’s employment practices have long been the subject of criticism. Workers are stringently monitored by managers who prod them to move more quickly as they load boxes and count merchandise. Bathroom breaks are timed, employees are discouraged from interacting with one another during their 10 to 12 hour shifts, and last year Amazon worried privacy and labor rights groups when it secured a patent for a wristband that could be worn by employees and which would vibrate if the worker made an incorrect move. 

“They treat us like robots,” one employee based in Lebanon, Tennessee told the Daily Beast.
