The state of California, along with city attorneys from Los Angeles, San Diego, and San Francisco, are suing Uber and Lyft for misclassifying hundreds of thousands of drivers as independent contractors under Assembly Bill 5.

Written by Assemblywoman Lorena Gonzalez, AB5 codified a decision by the California Supreme Court that required a company to treat its workers as employees, not independent contractors, if it failed to: (A) prove the worker is free from the company's control and; (B) performed work outside of the company's core business and; (C) able to regularly do the same work independent of the company.
