A handful of California Democratic lawmakers announced legislation Tuesday to allow drivers for rideshare companies like Uber and Lyft — who are classified as independent contractors — to join a union.

Assembly Bill 1340, authored by Assemblymembers Buffy Wicks, D-Oakland, and Marc Berman, D-Menlo Park, is the first bill to propose broad changes to the ride-hailing business since the state Supreme Court upheld industry-backed Proposition 22 last year. “We stand for the right of every worker to truly have a voice,” Wicks said at a Tuesday rally of rideshare drivers near the state Capitol, who gathered holding signs that read “Gig Drivers Union Now.”
