Ummmm...How exactly would you be able to enforce such a law, what would constitute work, what would the penalties be and exactly how would it be applied, particularly for salaried individuals? Would teachers be legally obligated to stop grading exams and lesson planning at home once they'd reached 40 hrs and barred from coming into work the next day lest they be hit with a sizable fine or be imprisoned for crimes against the Republic? Do CEOs get to count flight time between their corporate office and their "conference" in Barbados as time worked? Do firefighters have to drop the hose and high tail it out of the forest fire when they reach the mark? If a surgery goes longer than expected, does the surgeon have to leave the job half done? What about the guy working two minimum wage jobs?

I recall a case a few years ago where Walmart store worked around overtime and providing benefits to full time workers by having part timers punch out early. How do you prevent more of that type of pro bono work from taking place when you cap work hours? How do you keep under the table work and compensation from spiking? What about the incentive this provides to hire illegal labor. Because it's already illegal, their's no additional consideration for the weekly hour limit.
