( my own )
Suffice it to say Amazon does not care about employees, neither at the warehouses nor at their corporate headquarters.
When I was there a guy jumped off a building because they wouldn't let him switch off a toxic team. They also similarly tried to prevent me from switching teams when I was there.
A week ago I was at one of the Amazon retail stores and an employee there agreed that Amazon cares nothing for their employees. Obviously one should take this with a grain of salt as this is just a random statement from a random retail employee, but this is generally what I hear from Amazon workers both current and ex.
The general word on the street in Seattle is "Amazon sucks" to the extent I've heard Amazon employees referred to as Amholes.
