Finland's new Prime Minister Sanna Marin is proposing putting the entire country on a four-day workweek consisting of six-hour workdays.

"I believe people deserve to spend more time with their families, loved ones, hobbies and other aspects of life, such as culture," the 34-year old Marin said.  "This could be the next step for us in working life."

There's plenty of evidence that this is a great idea. 

Last year, Microsoft Japan revealed that a trial four-day workweek had boosted productivity by 40 percent.

In 2018, the New Zealand company Perpetual Guardian - a 240-worker firm that manages trusts, wills, and estates - ran an experiment with the four-day workweek.  By the end of the two month trial, staff stress levels lowered seven percent.  Before the trial, 54 percent said they could handle the work-life balance; after the two months, that number went up to 78 percent.  Other metrics including leadership, commitment, stimulation and empowerment, and they all climbed post-trial.
