Bring back the 40-hour work week - AlterNet - Salon.com
Drawing on 150 years of historical research and business data, this article argues that the modern expectation of 50-60+ hour workweeks is economically counterproductive and based on false assumptions about productivity. Knowledge workers have only about six productive hours per day, and working beyond 40 hours per week consistently produces fatigue-related errors, safety hazards, and reduced output that negates any gains from extra time in the office. The article traces how this consensus—accepted from the 1930s through 1960s by major corporations including Henry Ford—was abandoned in the 1980s when Silicon Valley's startup culture romanticized "passion" and extreme hours, a mentality that spread across industries despite research showing that brief overtime sprints lose their productivity advantage after eight weeks and create lasting burnout that takes weeks to recover from.
