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

Why “Give 100%” Is Corrosive: Sustainable Performance, Burnout, and Reserve CapacityHost 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%”).00:00 Why Give 100%01:06 Protestant Work Ethic03:18 No Evidence Just Inherited04:20 The Math of Depletion04:52 Four Day Week Proof06:59 Reserve Beats Extraction07:49 Unequal Starting Baselines08:08 Allostatic Load Explained10:25 Remote Work Stress Relief11:42 Neurodivergent Hidden Costs13:14 Masking and Autistic Burnout15:39 Self Care Myth16:15 Maslach Burnout Research19:32 Why the Norm Persists20:04 Sustainable Performance Science21:38 A Question for Yourself22:26 Evidence Based Changes22:59 Give 60% Closing23:11 Sign Off ★ Support this podcast ★
