Christina Maslach, professor of psychology at the University of California, Berkeley, has been studying the causes of burnout, and its impact, for decades. She says that, in a year when everyone feels overwhelmed and exhausted, it’s more important than ever for managers to recognize when and why employees are suffering and take steps to solve those problems. In her framework, burnout stems from not only large workloads but also lack of control, community, and/or reward and values mismatches. She notes that leaders have the ability to pull many of those levers to help their workers. Maslach is the author of The Truth About Burnout and a forthcoming book on the topic.
