Microsoft experimented with a 4-day workweek, and productivity jumped by 40%

Microsoft found that implementing a four-day workweek led to a 40% boost in productivity, the company announced as part of the results of its "Work-Life Choice Challenge."
As part of the experiment, Microsoft's Japan subsidiary closed every Friday in August, resulting in higher productivity than in August 2018, the company said.
Microsoft Japan closed its offices every Friday in August and found that labor productivity increased by 39.9% compared with August 2018, the company said.
Microsoft isn't the first to highlight the productivity benefits of a four-day workweek.
It's not just the employees who benefited from Microsoft's four-day-workweek experiment — Microsoft found that it helped preserve electricity and office resources as well.
