Here's my expectation ...
Some of these workers will walk away with overtime, so they'll make more money. They'll also wind up working under less-desirable (for them) conditions -- say, crazier "fractional" shifts, etc. -- and whatever benefits they have will be trimmed back.
Many more of these jobs that would have been filled with "managers" will now be filled with part-timers who don't get benefits. The people holding these jobs will be compensated less because they'll be, on the margin, less valuable. Further, as many of them will now have to piece together a living in multiple locations, their net earnings will be even lower.
And, finally, as the effects of this all play out -- some of them seen, some of them unseen -- you, or somebody like you, will be clamoring even more loudly about how we "need to do something for the working poor!" And some politician will give you a chubby by signing some other document, and the cycle will repeat itself.
I'm 99% confident about my first two points. That third one? That's a lead-pipe cinch, baby!
