According to Dr. Heidi K. Gardner and Brad Winn in a new article for the People + Strategy Journal (a Society for Human Resource Management publication), much work remains in diversifying the top layers of leadership in today’s companies.

This article looks at the different ways that mismanaged diversity undermines inclusive collaboration, and offers research-backed ways for senior leaders and board members to overcome the illusion of inclusion.
