Did Bezos care about warehouse worker safety when he ran things day to day? I thought there have been sporadic reports of warehouse worker mistreatment going back years, like that story about the one warehouse that had to have an ambulance parked outside to pick up workers who got heat stroke because it was cheaper than installing A/C. (No idea if that story's true. Just, this stuff has been circulating for a while. The new stories are no more or less credible, so I'm not changing my opinion of what's happening on the ground.)

Please explain how it's "sub par", which is different from "bad".
