**The key to advancing gender equality? Men.** Women are at a disadvantage. At home, they often face an unequal division of household chores and childcare, and in the workplace, they deal with lower pay, lack of credit for their contributions, roadblocks to promotion, sexual harassment, and more. And while organizations are looking to address these issues, too many gender-inclusion initiatives focus on how women themselves should respond, reinforcing the perception that these are women’s issues and that men—often the most influential stakeholders in an organization—don’t need to be involved. Gender-in-the-workplace experts David G. Smith and W. Brad Johnson counter this perception. In this important book, they show that men have a crucial role to play in promoting gender equality at work. Research shows that when men are deliberately engaged in gender-inclusion programs, 96 percent of women in those organizations perceive real progress in gender equality, compared with only 30 percent of women in organizations without strong male engagement. *Good Guys* is the first practical, research-based guide for how to be a male ally to women in the workplace. Filled with firsthand accounts from both men and women, and tips for getting started, the book shows how men can partner with their female colleagues to advance women’s leadership and equality by breaking ingrained gender stereotypes, overcoming unconscious biases, developing and supporting the talented women around them, and creating productive and respectful working relationships with women.
