Uber, Lyft, and DoorDash have joined forces to jointly oppose a new California labor law, Assembly Bill 5, which took effect on January 1, 2020.

The three companies have pledged over $90 million to advance a ballot measure that would repeal the law. Assembly Bill 5, in a test for the gig-economy, mandates that Uber, Lyft, and other employers must classify most of their workers, such as drivers, as employees and not independent contractors. Such a change in classification would threaten the ride-sharing giants’ business models and entitle such drivers to a minimum wage and other benefits.
