Microsoft Japan boasts 40% productivity jump thanks to four-day workweek experiment www.neowin.net

In a month long experiment this past August, Microsoft Japan saw a 40% increase in productivity levels by employees when a four day workweek was implemented.
Microsoft's “Work Life Choice Challenge” saw the firm close its doors on Fridays and its 2,300 staff enjoy a three day weekend to assess the merits of a reduced workweek.
This was thanks to meetings taking no longer than 30 minutes, and an increase in remote conferences.
Microsoft's Work Life Choice Challenge also included various self development and wellness schemes, with 92.1% of the employees giving positive feedback and saying they liked the four-day workweek.
Microsoft Japan says that although the scheme isn't permanent it plans to implement it this winter to encourage greater flexible working.
