No, that's not normally what a four day week means. It generally means less hours, but you also wouldn't normally expect moretotal stuff to get done, but you might expect a similar amount to get done (5 days worth in 4 days, not 6 days worth in 4 days!).

Now,if that's generally achievable is up for debate. I think most would agree 8 hours a day, 5 days a week is likely better than 10 hours a say, 7 days a week. But it's not obvious if a 30 hour week is better or worse than a 40 hour week.
