DEI Director Charley Downing and Iggy discuss the book Caste by Isabel Wilkerson. We explore the metaphors and reality of caste Wilkerson researched in the US and beyond. We also focus on applying what caste means in a practical sense as a foundation for our work, for Charley as someone tasked with addressing racial equity in the workplace, and for Iggy as a perspective on organizational policy that supports institutional toxicity.
