Young adults are throwing their support behind calls for a four-day workweek.

A new national survey from CNBC/Generation Lab of 1,033 people aged 18 to 34 found that an overwhelming 81% of respondents believe a four-day workweek would boost their company’s productivity, while 19% said productivity would decline.

Those results from the “Youth & Money in the USA” survey come amid discussions around the potential benefits of switching from the standard five-day U.S. workweek to a four-day cadence without a pay cut.

Some companies have begun testing the arrangement, and say it has mitigated employee burnout and strengthened business performance.
