Though strides have been made toward equity in the last few decades, gender and racial bias persist in organizations and in society. Even more disconcerting, Black women and other women of color are being held back more than their White counterparts. Most advice for women encourages individuals to speak up, be assertive, or lean in-to assimilate into a system modeled after White men. But we need collective action, where marginalized individuals work together, so all women experience the benefits of professional growth and equality. We need Shared Sisterhood, and anyone, regardless of gender, can join in. In this book, Tina Opie and Beth A. Livingston explain how to build this crucial alliance through vulnerability, trust, empathy, and risk-taking, so that all women can advance in the workplace and create systemic change. Balancing a mix of history, research, and real-life examples, this book encourages everyone to be a part of the sisterhood and push for gender equity that is equal for all.
