The 100% Myth: Why Giving Everything Is Costing You Everything

Why “Give 100%” Is Corrosive: Sustainable Performance, Burnout, and Reserve Capacity

Host Leslie Poston examines the phrase “give 100%” in American work culture, tracing it to Protestant work-ethic theology and arguing it became a management tool that moralizes maximum output despite lacking empirical support. The episode contrasts this norm with research on sustainable performance, citing shorter-workweek trials. Poston explains how “100%” ignores unequal baselines via allostatic load, highlights commute and remote-work effects, and details autistic burnout and masking costs. Drawing on Christina Maslach’s burnout research and WHO recognition, the script argues burnout is organizational, not personal, and advocates structural changes and operating below maximum (e.g., “give 60%”).
