On Friday, Uber pushed a new 21-page agreement on to all of its 400,000-plus drivers nationwide, forbidding them from filing a lawsuit in the event of a future labor dispute. Drivers were required to agree to the terms on their phones and could not accept any more fares until they did so.

As a result, the lawyer representing California-based Uber drivers in an ongoing class action lawsuit has asked a federal judge in San Francisco to immediately put a stop to the new agreement.

Under Uber’s new agreement, drivers are now supposed to only file for arbitration rather than sue or join a class action lawsuit. Unlike the public judicial system, arbitration is wholly private and almost always favors companies over people. Worse still, it makes class action cases nearly impossible, creating a situation where individuals en masse can rarely hold companies accountable for wrongdoing.
