Why is the notion that 'more hours mean more productivity' a flawed assumption in business?

Why is the notion that 'more hours mean more productivity' a flawed assumption in business?

Info

This myth stems from the industrial-era mindset that equates time spent with output generated. In reality, productivity is about value creation, not just time logged.

  • Diminishing Returns: Beyond a point, working longer hours leads to mental fatigue, poor decision-making, and increased errors.

  • Quality vs Quantity: More hours don’t guarantee better outcomes. Deep work and focus create more impact than busywork.

  • Burnout and Turnover: Overworking employees can result in disengagement, health issues, and attrition.

  • Lack of Innovation: Rest and downtime are critical for creativity and problem-solving.

  • Output Metrics: Businesses should focus on deliverables and outcomes, not just hours worked.

Modern productivity metrics favor goal-oriented planning, intelligent automation, and a results-based work culture over time-based measurement.
