Nancy Rothbard, a professor of management at the University of Pennsylvania’s Wharton School, draws a distinction between workaholism and working long hours. She explains the health consequences of being addicted to your work. She also gives practical advice for managing work addiction, whether it’s you who’s suffering, your direct report, boss, peer, or partner. Rothbard is the coauthor of the HBR article "How Being a Workaholic Differs from Working Long Hours — and Why That Matters for Your Health."
