This article examines how initiatives to increase diversity in corporations have largely been unsuccessful and why this has happened. Many companies have tried to make their workforce more diverse as it is seen to have multiple advantages over a monolithic workforce. However, despite decades of measures to achieve greater diversity, progress has been slow, and many of the initiatives have not delivered results. People of color and women remain under-represented in the leadership of most businesses. The reasons for this are complex, but it largely stems from unconscious biases, structural issues, and a lack of commitment to the cause. The article suggests that changes to corporate culture and the implementation of a variety of initiatives can help to address this problem.
