Google workers on Thursday expanded their rebellion against company practices, sending letters to three firms they say provide contract workers to Google, asking them to end mandatory arbitration for those workers.

The move follows a victory by Googlers who pushed the Mountain View technology giant to end forced arbitration for its own workers in March. Mandatory arbitration refers to the practice of requiring workers, as a condition of employment, to give up their right to sue in court over disputes and instead resolve them in negotiations that critics of the practice argue typically favor employers.
