Sixty-nine workers at the vigilante crime-watch app, Citizen, are unionizing with the Communications Workers of America. 

The workers petitioned for a union election with the National Labor Relations Board on September 22, and are waiting for approval to conduct a union election, according to the National Labor Relations Board filing. They are calling their union the Citizen Central Operations Union. A spokesperson for Citizen told Motherboard that the company does not support the unionization effort.
