Last election, Santa Clara (county, IIRC) had a ballot proposition up to change their labor law so that a business which needed additional hours worked would be required to offer them first to existing employees (potentially putting them over thresholds for things like full-time employment status) before they could hire any additional employees to work those hours.

It's a game of whack-a-mole, but if you want to get to living wage + benefits for everyone, that's kind of how you have to go about it, since businesses will always hunt for loopholes.
