> In a lengthy and heavily reported article, The Call said a warehouse employee contacted the Occupational Safety and Health Administration on June 2 to report that the heat index in the warehouse had reached 102 degrees, and that 15 workers had collapsed. The employee also said workers who were sent home because of the heat received disciplinary points.
> Eight days later, the paper said, an emergency room doctor at a local hospital saw enough Amazon employees suffering from heat-related injuries to call OSHA and report “an unsafe environment.”
> So many ambulances responded to medical assistance calls at the warehouse during a heat wave in May, the paper said, that the retailer paid Cetronia Ambulance Corps to have paramedics and ambulances stationed outside the warehouse during several days of excess heat over the summer. About 15 people were taken to hospitals, while 20 or 30 more were treated right there, the ambulance chief told The Call.
In a giant warehouse managed by a company with > 100k employees, things are not changed that quickly...
I wasn't a contract product picker either, I'm a Paramedic that helped staff the on-site medical clinic, which exists mostly for workers comp paperwork and the occasional emergency. (in 6 months, I responded to 2 actual medical emergencies.)
The warehouses were not overheating even in the Texas sun, we didn't have an ambulance sitting outside, and people weren't passing out. I'm not sure what was up with the one in the story but it definitely sounds like more of an exception than the rule. But that story of that warehouse just keeps coming up.
