Unfortunately, the author did not mention the name of the boss. Unless there is a personal consequence for management, this kind of garbage will keep repeating itself.
I would encourage the author to name his manager. Maybe the manager can provide his side of the story. I suspect that Amazon leadership principles won't help him in anyway.
There might not be a personal consequence directly attached to Amazon employment, but this certainly has impact from a career standpoint.
Mentioning the manager could inhibit him from further employment elsewhere, because once the HR Depts of other companies' start to gather background information on him, they'll think he's a whiner fingerpointer. You cannot exclude a person from employment just for that, but they'll find another reason to not hire him.
It doesn't drive change at Amazon, but it saves him unnecessary risk.
Fortunately he did not. I never mentioned the assholes, racists, rapists and liars I met professionally. It only throws back the dirt at you, and dirt keeps sticking.
