Benefits of Four-Day Workweeks: Microsoft Japan Study

Do you think the weekends are not enough time away from work? Do you tell yourself, “If I only I could have an extra day off work, then I can get more done.” These days, work-life balance has been a topic of interest for working less. There have been studies out there regarding the benefits of four-day workweeks. One of them will be discussed in this post. The idea of having shorter workweeks and workdays has simplified, with some companies looking at implementing more flexible work schedules.

Benefits of Four-Day Workweeks: Microsoft Study

Most recently, Microsoft Japan published a study that looked at flexible work options.  The study took place in August 2019, where the firm implemented a four-day workweek that its employees followed. This study is called the “Work-Life Choice Challenge 2019 Summer”. The research is in Japanese, so instead of interpreting the whole review, I will review some key findings from some articles I read about the results. The key findings from the study include:

1.) Four-Day Workweeks Resulting in 40% Jump In Productivity

2.) Positive Employee Feedback

3.) New Initiatives: Self-Development & Family Wellness Programs

40% Jump in Productivity

In the study of approximately 2300 employees, Microsoft Japan’s objective was to allow employees to work 25% fewer hours in a given week. The most prominent finding was that employee productivity increased to 40% (sales per employee measure productivity). During August 2019, the firm closed its office on Fridays, allowing employees to enjoy a three-day weekend. The move resulted in operation costs going down (less money to run facilities each day). There were shorter meetings at work (in this case, sessions were limited to a half-hour a day), and more remote conferences took place. Some impressive figures included 23% less electricity and 58% less paper printed each day. The costs of electricity and printing paper can run up high sometimes, so this was a unique cost-saving result.

Self Development & Family Wellness Programs

Along with providing flexibility for their employees, Microsoft Japan offered self-development and family wellness programs to accommodate work-life balance. As a result of employee feedback, the firm look into ways their employees could find better resources for their families. 92% of employees responded positively to the four-day workweek, saying it would benefit them and the firm further should it be implemented permanently.

Positive Employee Feedback

The study was similar to one that a company in New Zealand did back in 2018. The company tested a four-day workweek, and the results came back positive from their employees. Additionally, the culture in Japan is known as hardworking, and firm employee commitment to company success. Also, a 2016 study from the Japanese government found that around 25% of companies required employees to work more than 80 hours of overtime a month. This understanding has commonly been referred to as “karoshi” or death by overwork.

Reflections & Thoughts

Benefits Of Four-Day Workweeks- 3

Based on the results of this study, flexibility is something many people value these days. Work-life balance is something they want to prioritize in today’s workforce.

In my opinion, I like the four-day workweek schedule and the benefits of improving work-life balance. However, my concern is that the four-day workweek lasted for a month. I prefer Microsoft Japan to try it for longer than three months. That way, we can see how it would significantly change performance and culture. If the study went on longer, would the results be the same? Or, would there be a small dip in productivity a year later? As a long-term thinker, I like to look at the bigger implications of what could come out of the study.

On another thought, a four-day workweek may not be ideal on a year-round basis. For instance, if you work at a place where the work volume is higher, a four-day workweek may be useful as a short-term solution. The site I work at has a four-day workweek established for some employees. I work at a 24/7 mail processing center, where the work volume tends to be higher on the weekends. So what management decides is to implement a four-day workweek during these peak periods. Once the peak periods are over, we switch back to a traditional five-day work schedule for all employees. So this approach is an excellent example for companies to consider four-day workweeks. It is considered a temporary solution to fluctuating work volume.


Overall, the study conducted resulted in positive feedback from employees about flexible work options. The firm plans on testing out this approach next winter; ultimately, to see if they want to implement it in the long term. Working four days and having a three-day weekend allows employees for more personal time outside of work. If the model by Microsoft Japan lives up to their expectations, shorter days and fewer work hours could be the new norm in the modern workplace.

Do you find a work-life balance a priority in life?

Is the company you work at looking to implement flexible work schedules?

How is it improving your own work schedule?

  1. I love the idea of a 4 day work week. I don’t think it could be implemented where I work.

    The extra time though would be great for personal growth.

    • Thank you, Jocelyn. I’m glad to know you enjoyed reading this post.

      Yes, the four-day workweek sounds good for many who want a shorter workweek. That extra time spent on personal growth and learning would certainly be beneficial. If I had the choice, I certainly would take it.

      Thanks again for sharing your input- much appreciated!

  2. I really liked the idea of not just giving employees a longer weekend, but also implementing the family wellness programs. So often more time off work feels good because, unfortunately, not everyone enjoys their job and a lot of time even if you DO enjoy it, the stress of the work can cause imbalance in other places in ones life. I’m glad to see more companies putting employees well being higher on the priority list.

    • Thank you, Randi.

      I agree with your point about implementing family wellness programs. It would be very beneficial to have those types of programs to help with employee’s well being. Also, taking advantage of the time off does help give people a break from work. It takes off a lot of stress, as well.

      We’ll see how companies adapt and if they implement these types of programs down the road.

      Thanks again for sharing your thoughts- much appreciated!

    • Yes, I’m aware that’s the case in some countries. The four-day workweek (and shorter workdays) are getting positive responses. So eventually, it may happen for a lot of companies in the US. We’ll see what happens.


  3. I read with interest your post on the 4-day workweek. I wondered what the results of that study would be if it was done for more than 1 month. Would employees still feel they had time off if they had to have remote conferences on their time instead of company meetings on company time?
    A four-day work week is gaining in popularity in North America. Time will tell if it takes hold or not.

    • Thank you, Carolyn. You make some excellent points.

      Regarding your question, that’s still up in the air. I’m not sure how employees would feel if the study has gone for longer than a month. I think they would found the benefits immensely helping them, and maybe they’d be happier as well. For them, getting that right work-life balance would help out a lot.

      The remote meetings would be interesting to look into, particularly on company time. So those are the right questions to consider.

      Thanks again for sharing your thoughts- much appreciated!

  4. I really like the idea of a four-day work week and the family wellness programs, but I agree with you that we’ll have to see if there’s any side effects to it in the long run. But I know I’d also love to see people be able to have a good livelihood without becoming workaholics. So I’m glad that companies are really looking at how to really help their employees.

    • Thank you, Kelby. I’m glad to hear you enjoyed reading this post.

      It’ll be interesting to see what the side effects are like down the road. I think balancing it out the right way would be a great start. But time will tell, for sure.

      Thanks again for sharing your input- much appreciated!

  5. I’m really glad that companies are even exploring this four-day workweek (or other methods if they can’t do it all the time.) To me it shows they’re really starting to look at how to keep their employees truly happy. People should be able to live well without having to work themselves to death.

    • Thanks again, Kelby. You make some excellent points.

      We’ll see what happens in the workplace moving forward.

      Again, I much appreciate your comments!

  6. I just had a friend tell me a couple of days ago that this is likely to happen in the UK if a particular party wins the election (not sure what party) as I am not that much into the politics. When he first mentioned a four day work week I was thinking this is jokes and just an excuse for the next generation to become lazier and lazier and productivity going down. The study results are both surprising and amazing.

    I would absolutely love having an extra day off work, as long as they do not decide to cut salaries due to less days work. However, if productivity is going up then I assume salaries are certainly not cut as if it was it would define the point and would create a lack of motivation instead of a boost in productivity, which here is clearly the case.

    I am curious however how it will affect those that work for an hourly rate. Those that get paid monthly in a permanent position will not be affected by it, but I am curious about the work around for those that gets paid by the hour.

    • Thank you, Schalk. You make some excellent points about work hours and the workweek in general.

      Regarding your questions, I’m not sure how that would work with hourly workers. Maybe there are some similarities but differences as well. That would be something I’d want to read more on, so time will tell.

      Other than that, thanks again for your thoughtful input- much appreciated!
