To make a wide reaching and vague law that doesn't fit every industry is crazy. Are Amazon warehouse workers or delivery drivers really as productive in 32 hours as they are in 40 hours? No...there is no way that is possible. This might work for some big cubicle farms...but not for manufacturing type industries.

Is this the only thing anyone is ever concerned about? How about employee general well-being? The fact that average worker wages have been absolutely stagnant while average worker productivity has soared since the 70's? Maybe it's time workers won something instead of just getting squeezed for more productivity.
Are they productive because THEY are more productive or because tools and systems have allowed for increased productivity? Should Ford assembly line workers have been paid more because his assembly line system was easier and more productive? He ended up paying them more voluntarily, but would you really want to mandate that?
