Amazon has attracted widespread criticism for poor working conditions by both current employees, who refer to themselves as Amazonians,[178] and former employees,[179][180] as well as the media and politicians.

Loading-bay doors were not opened to allow in fresh air, due to the company's concerns over theft.[181] Amazon's initial response was to pay for an ambulance to sit outside on call to cart away overheated employees.[181] The company eventually installed air conditioning at the warehouse.[182]
