Lean In meets Freakonomics. How men and women can close the gender gap in the workplace.

We all agree that men and women think and behave differently. Here, at last, is a book that shows both sides what to do about it.

When Joanne Lipman wrote the article 'Women at Work: A Guide for Men' for Wall Street Journal, it immediately went viral. When the response continued to grow, she realised just how crucial an element was missing from the gender equality debate in the workplace: without men participating in the conversation, women can lean in all they want...but all they'll do is fall over.

Lipman was contacted by scores of corporations and businesses around the world, where men (yes, men!) were eager for the playbook on how to work better with women and how to make their companies work better for women. As she began speaking on the topic and continued to delve into the science, Lipman realised that there was an awful lot to say to men about women at work.

In Win Win: When Business Works for Women It Works for Everyone, Lipman takes a 'no shame, no blame' approach to this thorny topic. Diving deep into the wide range of government initiatives, corporate experiments and social science research (and a few ongoing lawsuits along the way) she offers new revelations culled from the Enron scandal, from brain research, from transgender scientists, and from Iceland's campaign to 'feminise' an entire nation.

Packed with fascinating and entertaining examples, including how Google reinvented their hiring process after their famed open-ended questions ('How many piano tuners are there in the entire world?') produced, to their surprise and dismay, an overwhelmingly male work force, and how the latest research on the significant differences between how men and women email, Win Win is a rallying cry for both men and women to finally take real steps towards closing the gender gap at work.
