"The most important business book of the year" - Esquire There's never been more discussion around diversity and inclusion in the workplace. From gender pay gaps and the #MeToo movement to Black Lives Matter, it seems that every organization has finally recognised that lasting change needs to happen. Various studies show that the most successful and productive senior management teams are those which are truly diverse and eclectic. Yet there remains only 8 female CEOs of FTSE 100 boards, and only 10 BAME people working in leadership roles across companies in the FTSE 100. While there has been a clear shift in attitudes, actual progress towards more inclusive workspaces has been excruciatingly slow and, in some cases, has ground to a halt. Following extensive research and interviews at over 200 international businesses, Kathryn Jacob, Sue Unerman and Mark Edwards have discovered one major problem that is holding back the move towards greater diversity: why aren't the men getting involved? Most men are not engaged with D&I initiatives in the workplace - at one extreme they may be feeling actively hostile and threatened by the changing cultural landscape. But others may be unmotivated to change - recognising the abstract benefits of diversity but not realising what's in it for them. The time for change is long past. Belonging is the call to action we need today -the tool to turn the men in power into allies as we battle discrimination, harassment, pay gaps, and structural racism and patriarchy at every level of the workplace. The lessons in this book will help us work together to build a better workplace where everyone feels they belong.
