The workers fired from Google for staging an office sit-in to protest the company’s contract with Israel have filed a complaint with the National Labor Relations Board, alleging the company violated their labor rights by terminating them.

The workers in the complaint are demanding their jobs be reinstated with back pay and the company release a statement saying it will not violate workers’ rights to organize. In an email the day after the sit-ins, Google CEO Sundar Pichai said work is not the place to debate politics, but the protesters argued in the lawsuit they were discussing working conditions, including the fact that the company has a $1.2 billion contract with Israel, not politics.
