Introducing the 20-hour work week

Story highlights

  • Author and development expert suggests we must drastically reduce working hours
  • Companies are beginning to support the practice and studies show it can improve performance

(CNN)After years on a treadmill of stressful and demanding assignments for high-powered institutions such as the World Bank, development and policy expert William Powers hit a brick wall.

The self-confessed "work junkie" took a year out living off-grid in a North Carolina cabin, experimenting with a slower lifestyle, and upon returning to his native New York, decided that he could not go back to the grind.
    "I could never work 9-5 again," says Powers. "That kind of work seemed like a form of slavery -- giving up your mental, emotional, and intellectual capacities."
    Powers slashed his working hours from over 50 a week to just 20, limited to Tuesdays and Wednesdays, with a five-day weekend. His time was split between freelance consulting, writing and speaking jobs.
    Two theories were critical to making the new arrangement work. 'Parkinson's Law' - that work expands to fill the time available, and entrepreneur Richard Koch's '80/20 Principle,' which argues that we achieve 80% of productivity in 20% of our time -- and vice versa.

    "I gave myself very short deadlines on everything I needed to do," says Powers. "I thought about what were the most effective things I could be doing and fired other clients. I got rid of superfluous work strands, and though my hours were reduced by 60%, my income went down by only 20%."
    Strictly adhering to the new routine -- observing technology fasts and ignoring out-of-hours emails -- recharged the New Yorker's frazzled psyche as he was able to spend time with his family, get out of the city, and eat well, but also ensured that his reduced working hours were put to good use.
    "I would get to my virtual office Tuesday morning refreshed," says Powers. "I would be focusing on tight deadlines and because of 80/20 I would be doing the work that was most interesting to me."

    Work less, achieve more

    With a new release of his book "New Slow City," Powers wants to convince others of the benefits of changing routine.
    He argues that a new paradigm is needed to replace the eight-hour, five-day week that has endured since Henry Ford introduced it in 1914. The productivity of US workers has almost doubled since the 1970s but Americans are still working some of the longest hours in the world.
    "I realize not everyone can do it because the cost of living is so high in cities that some people are just scraping by with two jobs," says Powers. "But if cultural creatives and opinion leaders make the change it can (eventually) flip to everyone."
    Powers went cold turkey after being a workaholic but recommends that others make more gradual adjustments, such as experimenting with shorter deadlines and taking the saved time off:
    "In the U.S. our identities are shaped around two things; being workers and consumers. It's about opening up little spaces for creativity and free time that will help you to go in a new direction."
    Powers is far from alone in promoting new practices. The "Gothenburg experiment" has seen the Swedish city implement a six-hour day for public workers, with many private firms joining in, on the basis that what is good for staff will improve their work.
    "Today we get more done in six hours than comparable companies do in eight," wrote Maria Brath, CEO of tech start-up Brath. "We believe it comes with the high level of creativity demanded in this line of work. We believe nobody can be creative and productive in eight hours straight."
    Brath points to rising revenue since the shift as evidence of its value. She also notes benefits beyond staff morale, such as offering an advantage in recruitment and retention, and improved profile and reputation for the company.
    Forward-thinking U.S. companies such as 37signals and Treehouse have implemented and maintained four-day weeks, noting an improvement in staff morale, retention and quality of output.

    The global slow down

    Recent studies support the shift, with OECD figures showing that shorter weeks in France and Germany have resulted in higher productivity per hour than British counterparts working longer. The correlation extends further to show that productivity sharply declines from the second hour.
    Excessive hours have also been shown to be counter-productive, with Stanford Professor
