the claim

Shorter work hours increase productivity per hour.

the verdict
INSUFFICIENT LEANING
Recorded sources
6 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that shorter work hours increase productivity per hour?

Unclear. Several items partially support the claim: a 2004-11 workweek-reduction study found output per worker rose 1.5% in manufacturing, and a resident study found shorter shifts yielded more patients per hour. Other items report shorter schedules maintained or improved output, but none measures productivity per hour across the general workforce.
