One of the true paradoxes of male allyship is the consistent social psychological research evidence showing that when men advocate for women or call out gender inequalities, they are perceived to be more credible because they are not acting in self-interest. [...] It's time for men to open their eyes to this opportunity and privilege and use it. (Good Guys, page 10)
Good Guys is a very thorough guide in how to be a better ally to women, particularly in the workplace, but also at home. This is no lazy, hand-wavy introduction to the subject; there are 14 pages of references at the back that make sure each page packs a punch. It's an important book that I hope many men will pick up and utilise.
The book is split into three parts: interpersonal allyship, public allyship and systemic allyship. In each section, the authors guide you step-by-step through different ideas and ways in which to develop your allyship skills, and the end of each chapter has a little section that sums up the most important ideas covered. It really couldn't be laid out in a way more easy to understand, and I wish I could give a copy to every man in my office.
I especially appreciated the inclusion of intersectionality, highlighting that not all women are the same, that some feel the need to hide parts of their identity for fear of negative reactions. This is something I do, as I don't feel safe bringing my whole self to work.
