I've seen several cases here where going from 40 to 32 hours to have time for kids (very very common in NL) has kept the same or better productivity. Of course those were all desk jobs, where it's not about exactly how many hours you're typing code or writing ideas but about the output. I expect it to be less applicable for assembly line kind of work.
