Seattle's landmark law that lets drivers for ride-hailing companies decide if they want to bargain collectively was set to go into effect today, but an Uber subsidiary has sued to block key rules of the ordinance governing which drivers get to vote on unionization and other key rules. From a report: Uber subsidiary Rasier filed a petition in King County Superior Court Tuesday to block recently-published rules from Seattle's department of Finance and Administrative Services that cover issues like which drivers get a say in whether they want to unionize, working conditions subject to bargaining and how an organization gets certified to represent drivers exclusively. In court documents, Uber called the city's process flawed and asked the court to suspend the new rules. Uber wants the city to go back and tweak the rules so that they better reflect driver conditions in the ride-hailing industry. "The City failed to provide comprehensive rules and disregarded the facts and circumstances of drivers and the industry," according to Uber's petition. "Moreover, the Cityâ(TM)s rules are inconsistent with fundamental labor law principles ensuring every worker has a voice in whether to be represented by a labor organization."
