Yep seen this article b4. Basically not many management are willing to put it as "management/superior failure". It reflects badly on themselves as well. Esp in MNC where nobody is boss, all work for wayang, even worse. If you are HR, and your attrition summary report points to dissatisfaction with Head Of Dept, what can you do? the most they can do is rotate a bit so that diff manager take the subordinate and see how.
