Women spend their working lives adapting to an environment set up for men, by men: from altering the way they speak to changing the clothes they wear to power posing. But still the gender gap persists. And once you see it - women being overlooked, interrupted, their ideas credited to men - it's impossible to ignore.

But it needn't be this way.

Diving deep into the wide range of government initiatives, corporate experiments and social science research Joanne Lipman offers fascinating new revelations about the way men and women work 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 - from the woman behind the success of Tupperware to how Google reinvented its hiring process - That's What She Said is a rallying cry to both men and women to finally take real steps towards closing the gender gap.
