By neglecting to negotiate her starting salary for her first job, a woman may sacrifice over half a million dollars in lost earnings by the end of her career. Yet, as Professor Linda Babcock discovered, men at her own university asked for higher pay eight times more often than women with the same qualifications. Combining fascinating research with revealing commentary from women at all career levels, Babcock and Laschever explore the many personal and societal reasons why women so often find it hard to ask at home or at work - even when they negotiate effectively on behalf of others. The authors also show how women can develop a negotiating style that fits their values, and how businesses, schools, and other institutions can help.
