Most but not all EU states. And many other EU states are very close to US productivity while they're working less http://time.com/4621185/worker-productivity-countries/ So threatening worker's lives and not having a single day of vacation or sick time are clearly not the reason for higher productivity. They're just there to make people's lives more miserable and continue a culture obsessed with control and enslavement. Anyway, productivity only matters to business owners. Workers couldn't give a shit. They just can't get their concerns addressed because we live in a plutocratic oligarchy which hardly qualifies as a democracy.
