If productivity is down in your organization, it may be a sign that at least some employees are unmotivated and unhappy—and that other employees are feeding on that dissatisfaction, further eroding productivity and creating attrition. On this episode of The McKinsey Podcast, McKinsey senior partner Aaron De Smet and partner Angelika Reich talk about McKinsey’s latest research on employee productivity and their perspectives on a few types of workers, ranging from those who bring fellow employees down to those who raise them up.
