Around 18 million adults in the U.S. alone suffer from long Covid, a chronic illness with a wide range of symptoms and severity. With approved therapies a long way off, workers with long Covid often struggle in silence. And most companies have neither a good understanding of the situation nor effective policies in place, say MIT research scientist Beth Pollack and Vanguard University professor Ludmila Praslova. They share the conditions associated with long Covid, what life is like for those workers, and the accommodations and flexibility they recommend HR leaders and organizations implement. Pollack and Praslova are coauthors with researcher Katie Bach of the HBR Big Idea article “Long Covid at Work: A Manager's Guide.”
