It is now accepted wisdom that increasing the diversity of your workforce in any dimension can improve both organizational culture and performance. But one group — people living with intellectual, developmental, and physical disabilities — continues to be overlooked by many companies. Luisa Alemany, associate professor at London Business School, has studied workplaces that do recruit and hire employees with disabilities and found that it can be a true source of competitive advantage. She explains four main ways this talent strategy benefits the firm. She’s the coauthor, along with Freek Vermeulen, of the HBR article “Disability as a Source of Competitive Advantage.”
