We could also stick with the age-old seven-day arrangement by working three days and taking four off ~ better yet!

Four days on and three days off would be OK by me, though; no need, really, for that extra eighth day to extend the weekend.

Even a workweek of four 10-hour days would be preferable, to many folks, to the current five eight-hour day arrangement. Just as many hours (40), but more free time in terms of full days.
