Three-day weekends for employees at Microsoft Japan proved to result in a massive boost in productivity, according to a report.

The tech company found that productivity levels skyrocketed nearly 40% when it closed its doors on Fridays in August as part of a month-long challenge, CNBC reported.

During the month of reduced workweeks, the company saw a 39.9% rise in sales per employee compared to August 2018, according to the report.

The tech giant attributed the huge boon in part to capping meetings at 30 minutes and employees hosting more remote conferences.

Microsoft Japan’s 2,300 employees also largely supported the better work-life balance — with 92.1 percent saying that they enjoyed the four-day system, the report said.

The shorter workweek also saved the company money with the firm using 23.1% less electricity and 58.7% less paper.

Though there are no immediate plans to make the reduced workweek permanent, the company said they’ll be hosting a similar challenge this winter, CNBC reported.
