I have worked in Amazon for many years now in India. Jeff himself doesn't seem interested in taking work culture seriously. I have never seen any interviews of him after NYC article where he accepted that something was going wrong and needs to be fixed. Instead he turned the whole debate into work-life harmony rhetoric.
In India, the situation is far worse than US. There is less transparency and more opportunities by senior leadership to rule with an iron fist without any accountability. Concerns are suppressed instantly. One might have been an excellent employee for couple of years but for some reason if you are not on top of your game for even a quarter, you will start hearing complains from everyone and the situation can go upto PIP (Performance Improvement). The culture completely lacks the emotion of "Let me help you". It is heavily influenced by politics and survival of the fittest which might be fine for a small period but takes a toll on you in long term. Probably this explains why attrition is so high in Amazon.
