Supreme Court upholds California worker law AB5.

The US Supreme Court has declined to hear a challenge to California's AB5 law, which classifies political signature-gathering "doorknockers" as employees entitled to payment of wages by the companies that hired them. The law defines workers as employees rather than independent contractors if they are in the same business as the hiring company, or the company controls their activity. The court has previously left the law intact in two other cases. The law has been challenged by freelance journalists and photographers, trucking companies, and ride-hailing companies such as Uber and Lyft.
