LOS ANGELES (AP) – Uber, Lyft and other app-based ride-hailing and delivery services have prevailed in their expensive gamble to keep drivers classified as independent contractors. Proposition 22 pitted the powerhouses of the so-called gig economy, including DoorDash, Postmates and Instacart, against labor unions. It’s the most expensive California ballot measure ever – more than $225 million was spent, most by the gig companies. The measure creates an exemption to a state law that would have made drivers eligible for benefits that come with being company employees. Drivers who supported the measure said they enjoy the freedom of being independent contractors who can set their own hours.
