That seems like the sort of rule that a government could apply to itself, but very unlikely to successfully change nongovernment company behavior. If governments (city, state, federal, etc.) really want to see part-time versus full-time employees treated more similarly, the way to do that is to reduce the differences between them. Of course this goes straight to the heart of many of our difficulties around all these things: the legacy-of-WW2-wage-controls connection between full-time employment and expensive (health insurance mostly) benefits. If that ever got fixed it would also fix many other things.
