The "8 hour day" was passed in the US in 1916, but apparently didn't become a nation-wide rule until 1938.

The economy has changed an awful lot since those days...
In a way it's unfortunate that 8 divides into 24 evenly. There are several ways to reduce hours and thereby enable more positions, but all of the choices seem to be less natural:
6 or 7 hours x 5 days?
5 hours x 6 days?
10 hours x 3 days?
Since manufacturing isn't as big a part of the economy as it was, the concern about having 3 shifts a day shouldn't be as large.
The last two choices makes some sense - Have the business day be 10 hours but the work week be 6 days: and run 2x5 hour shifts for 6 days, or 1x10 hour shift with 2 3 day per week teams. The 5 hour day might also support the ideas that some have of keeping kids in school 6 days a week.
Since some hospitals run 12 hour shifts, there are obviously ways that the system could be tweaked for certain circumstances.
Presumably someone has already looked into this...
Some say that since the work-week is already effectively 33 hours, we might as well make it official:
