This is an excellent book on how power is use in the workplace. Many of the examples echo experiences I've had in my career. I wish I had had the knowledge in this book year ago.
The negative reviews of this book say more about deficiencies in the reviewers than deficiencies in the book. This is a book about the – at best – morally ambiguous techniques people use to obtain and retain power. For many readers, the experience of having those techniques articulated is repugnant, and their reaction is to blame the messenger.
The sad fact is that at times power is achieved with dirty tricks. You’re better off knowing about these tricks; otherwise, you’ll be blindsided. For example, one case provided in the book was about an employee who was fired because she was too competent, and was a threat to her new boss. The exact same thing happened to me early in my career. And I’m not just relating my opinion of the case. A decade after the incident I encountered my boss’s boss on a flight I was taking. She apologized to me. In the months after my firing it had become clear that my boss was incompetent and was making up lies to protect herself.
It can be a cruel world out there. The information in this book can help you defend yourself.
