In the vein of Tim Wise’s White Like Me and Sheryl Sandberg’s Lean In, The Time Has Come —by co-founder of the White Ribbon campaign Michael Kaufman — offers a plain-spoken and forthright look at why and how men must actively fight for gender equality.

From founding the White Ribbon Campaign, the world’s largest organized effort of men working to end violence against women, in the early 1990s, to his appointment as the only male member of the G7 Gender Equality Advisory Council, Michael Kaufman has been a major figure in promoting social justice and women’s rights for decades. Now, in The Time Has Come, he issues a stirring call for men to mobilize in the movement for gender equality.

Weaving together sociological data, personal experiences, and insights gleaned from decades of work with governments and NGOs around the globe, Kaufman explores topics ranging from domestic violence to parental leave, grappling with the ways in which a culture of toxic masculinity hurts women and men (and their children). Informative and provocative, The Time Has Come demonstrates how real gender equality creates advancements in both the workplace and the global economy, and urges men to become dedicated allies in dismantling the patriarchy.
