At the World Economic Forum in Davos, IMF Chief Christine Lagarde called the advancement of women the greatest economic opportunity of our time. She was recognizing what Katty Kay calls Womenomics, the extraordinary value of women in the workforce. Global studies show that companies who employ more senior women make more money. But too many women in their mid-thirties hit the brick wall of kids vs. career and decide to leave the workforce. We can’t afford to keep losing them. Katty marshals evidence from employers large and small to show how it’s possible to help women meet the demands of family and career and keep these valuable contributors in the workforce. What starts as talent retention initiative becomes a profit bonus any company would be happy to have. Katty’s talk inspires women and provides a practical guide to employers.
