The lawsuit says Uber is unlawfully pressuring drivers via the app to support the Nov. 3 company-sponsored ballot measure, known as Proposition 22.
Uber rejected those claims.
Prop 22 would overwrite California law AB5 intended to force Uber, Lyft LYFT.O and other app-based companies to classify workers as employees, entitling them to benefits including minimum wage, overtime pay, health and unemployment insurance.
