The rapid expansion of artificial intelligence technology is creating, destroying, and changing jobs. And Harvard Business School professor Raffaella Sadun has been studying how leading companies are training and reskilling employees for this new paradigm. She says many firms underestimate how quickly and significantly workers will need to be reskilled and leave this effort to the HR department. Instead, she explains leaders and middle managers across the company are essential to manage this change. With Jorge Tamayo and Leila Doumi of HBS and Sagar Goel and Orsolya Kovács-Ondrejkovic of the BCG Henderson Institute, Sadun wrote the HBR article “Reskilling in the Age of AI.”
