Money & WorkFact
Countries with short working weeks are often the most productive.
Labour productivity is economic output per hour worked, not per person. Grinding through long hours doesn't automatically create more value; past a certain point, each extra hour yields less. Long-run prosperity comes almost entirely from productivity growth: better machines, training, organisation. Not from longer attendance.
Useful: Measure your workday by results, not by hours in the office.
