Problem now is a lot of the remaining workers at twitter are immigrants on a work visa. California is an "at-will" employment state, meaning employers can fire workers for anything except things that relate to collective bargaining from an established union. Really easy to get fired for unionizing, because they employer can just claim it's for a different reason. Then you don't have a work visa and have to leave the country. Only option there is suing in a federal court.
Even if they get unionized now and the paperwork goes through, the NLRB can't legally do anything if a work visa is revoked from an immigrant.
