Isn't It 20 % Less Work?

A new iceland study that came out of 25 hundred people that worked four day work weeks over several years, and they found that they were as productive. They wereactually happier and had better health outcomes. Ow we're seeing countries like spain, portugal, new zealand, a kick starter isnot a country, but a business that's that's doing the four day work week. So i can im that the most obvious question would be like, w if i work one day less, isn't that going to be you now, a 20 % decrease in productivity over all? How do those numbers play out?"
