Glass Half-Broken

Why the gender gap persists and how we can close it.For years women have made up the majority of college-educated workers in the United States. In 2019, the gap between the percentage of women and the percentage of men in the workforce was the smallest on record. But despite these statistics, women remain underrepresented in positions of power and status, with the highest-paying jobs the most gender-imbalanced. Even in fields where the numbers of men and women are roughly equal, or where women actually make up the majority, leadership ranks remain male-dominated.The persistence of these inequalities begs the question: Why haven't we made more progress?In Glass Half-Broken, Colleen Ammerman and Boris Groysberg reveal the pervasive organizational obstacles and managerial actions—limited opportunities for development, lack of role models and sponsors, and bias in hiring, compensation, and promotion—that create gender imbalances. Bringing to light the key findings from the latest research in psychology, sociology, organizational behavior, and economics, Ammerman and Groysberg show that throughout their careers—from entry-level to mid-level to senior-level positions—women get pushed out of the leadership pipeline, each time for different reasons. Presenting organizational and managerial strategies designed to weaken and ultimately break down these barriers, Glass Half-Broken is the authoritative resource that managers and leaders at all levels can use to finally shatter the glass ceiling.
