Proposition 22 is a California initiative sponsored by Uber, Lyft, DoorDash and other gig work platforms that would exempt app-based ride-hailing companies and food delivery companies from a new state law that requires them to classify drivers as employees instead of independent contractors. Gig companies have poured nearly $200 million into the Yes on Proposition 22 campaign, making it the most expensive ballot initiative in state history. They’ve threatened to leave California or dramatically raise prices if it doesn’t pass, and a loss could embolden other states to insist that app companies hire their drivers. Molly Wood speaks with Sam Harnett, a reporter for KQED in San Francisco.
