California lawmakers approved a landmark bill Sept. 10 requiring companies to designate freelancers or independent contractors as employees.

Passed by the California Senate this week, the bill would extend labor protections and employee benefits like health care, overtime and minimum wage to many workers formerly considered contractors. The measure is expected to be signed by California Governor Gavin Newsom and go into effect Jan. 1.

Starting then, associations that use freelancers in California may need to reclassify these workers as full-time employees entitled to employee benefits. This would apply not just to associations headquartered in California but any U.S. association that employs contractors in California.

The legislation was written by Assemblywoman Lorena Gonzalez, who is a labor advocate and a candidate for California Secretary of State in 2022. Gonzalez said she wants to codify a 2018 state Supreme Court ruling that said contract workers at delivery company Dynamex were entitled to the benefits of regular employees. The court decision created the “ABC” test to help classify workers in California.

Though it would impact a broad range of industries, Gonzalez’ primary target in creating the legislation are app-based employers like Uber, Lyft, Postmates and others that classify their drivers as freelancers and don’t provide employee benefits like sick time or health insurance.

“Today the Legislature made it clear: we will not in good conscience allow free-riding businesses to profit off depriving millions of workers from basic employee rights that lead to a middle-class job,” Gonzalez said on Tuesday. “It’s our duty to look out for working men and women, not Wall Street and their get-rich-quick IPOs.”

The bill exempts some occupations, including doctors, dentists, lawyers, engineers, accountants, architects and realtors. For many other occupations, the bill makes the “ABC” test the standard for determining employment status in California. The test is far stricter than federal regulations for determining employment status. It states that a worker can only be considered an independent contractor if they are: free from the “control and direction” of the company they work for; performing work that is “outside the course” of the company’s usual business; and have their own independently established trade, occupation or business.
