Gov. Gavin Newsom signed a measure, to take effect in 2020, making it harder for industries to treat workers like contractors instead of employees who are entitled to minimum wage and other benefits. Uber, Lyft and DoorDash have said they'll spend $30 million to put an initiative on the 2020 ballot to overturn the law.
