Also, please bear in mind that CA legislature has already exempted wide and arbitrary swathes of industry from AB5, seemingly based on each industry's political clout. While I wish for better worker protections than prop 22 provides, AB5 was bad legislature and implemented in a less-than-above-board way.
disclosure: I do work for a gig company, opinions are my own, etc. personally I want all the workers unionized, everywhere.
