Women make up fewer than 10% of national leaders worldwide. Behind this eye-opening statistic lies a pattern of unequal access to power. Through conversations with some of the world’s most powerful and interesting women—including Jacinda Ardern, Hillary Rodham Clinton, Christine Lagarde, Michelle Bachelet, and Theresa May—Women and Leadership explores gender bias and asks why there aren’t more women in leadership roles.

Speaking honestly and freely, these women talk about having their ideas stolen by male colleagues, what it’s like to be called fat or a slut in the media, and what things they wish they had done differently. The stories they tell reveal vividly how gender and sexism affect perceptions of women as leaders. Using current research as a starting point, Julia Gillard and Ngozi Okonjo-Iweala—both political leaders in their own countries—analyze the lived experiences of these women leaders. The result is a rare insight into life as a leader and a powerful call to arms for women everywhere.
