A very famous slogan among union organizers and such was "8 hours of work 8 of rest, 8 to do as we please". If you look into it this is also why certain sleep scientists are so insistent that 8 hours is enough sleep, because that's the amount most 9 to 5 workers get.

The problem is 8 hours of constant work is still way too much for the human body and it slowly hollows you out from the inside. You can often work more if the work is fulfilling and you aren't alienated from the products of your labor, but in a modern industrialized society that is almost never the case and working much more than 8 regularly will still shred your mind.
