Uber asks drivers to sign agreement banning them from joining class-action lawsuits

San Francisco-based Uber is asking all of its drivers to sign a legal agreement, banning them from joining class action lawsuits against the company.

The ride service sent the 21-page document to drivers nationwide yesterday.

The new agreement requires drivers to enter into arbitration.

Critics are questioning the timing of the agreement.

It comes just two days after a Federal Judge's ruling that expanded the class of California drivers that can take part in a class action suit against Uber.
