I feel for all of you in this thread that work at Amazon and complain of the poor conditions. There are no shortage of stories that point to a very large problem in that company, for certain. However, I believe the underlying theme, if there is one, is incompetent Management and Leadership.
This is systemic in Technology companies because, to me, the “bean counters” try to run the companies like a basic Manufacturing organization of commodities where line items and people are substitutable things and can be dialed and tweaked at the planning stage.
