"Babcock and Laschever cut to the core of the differences between men and women and their willingness to negotiate. They demonstrate both the financial costs to women and the impact on society as a whole. This book is a must read for both men and women who negotiate in their work and private lives. It shows women how to think about opportunities to negotiate and ways to overcome the tendency to avoid negotiation. It provides men with unique insights into the female perspective on negotiation."
