4 Day Workweek Versus 6-Hour Workday — Which Is Best?

We ran an experiment to find out.

The four-day workweek is making headlines again.

It first made the rounds back in 2008 when Utah state government employees began working ten-hour days from Monday to Thursday. A decade later, in the summer of 2019, Microsoft Japan trialed a four-day workweek, and it noted a 40 percent increase in sales per employee before curiously returning to the five-day workweek.

Now, Buffer, a tech company with 89 employees, is igniting the conversation again, particularly as the pandemic, remote work, and the blurring of lines between home and work has resulted in people working, on average, longer hours than ever before.

In response to these employee stressors, Buffer gave its employees an extra day off each week without reducing pay. The experiment has been so successful that it is still in play a year later.

Iceland, too, ran a comprehensive five-year study involving 2,500 workers. Their working week was reduced from 40 hours down to 35 to 36 hours, noting no loss in productivity and improved wellbeing. NPR reports that 86 percent of Iceland’s workforce has now moved to shorter hours or has the right to negotiate doing so.
