Last year, an Uber driver filed a class action lawsuit against Uber claiming that that they were misclassifying employees as independent contractors under AB5 but the passage of Prop 22 has Uber calling for a dismissal. Prop 22 exempts app-based companies from AB5 if they meet certain conditions. A judge has ruled that the arguments from the plaintiff and Uber have been insufficient and a renewal of their claims will be expected during summary judgement.
