Any large company is going to have abusive individuals in it. I think the real issue this story illustrates is that when people are brought over on work visas they have no leverage with their employer.
As an American citizen software engineer my boss knows that if I'm unhappy I will just leave. But the boss of someone on a work visa knows they can do pretty much whatever they want to them and the employee is just stuck.
So we need to change the work visa system so those employees aren't in such a vulnerable position. How exactly? I don't know..
That, and Amazon's processes to prevent engineers from this abuse from their managers.
No, the author lists a whole bunch of names from HR. That's not just an abusive boss, that's an abusive boss protected by HR, which makes it a story about Amazon.
I worked at Amazon and never had any issues like that. In fact, my experience was completely opposite and I had several wonderful bosses, great co-workers, awesome environment and fun things to work on.
I'm certain there are many stories like mine. That doesn't matter at all, as long as there's one case like Oleg's.
