Hungary is second on the most hours worked list, and also second on the least productive list.
It’s not at all surprising knowing Hungarian work ethics (both on employers’ and employees’ sides). I think it’s specific of post socialist countries – during long decades of full employment economy people learned well how to pretend to be working. It explains why none of those states are on the most productive list.
And in general, there seems to be an inverse connection between number of hours worked and productivity.
