Workers apart of the United Steelworkers union representing the locked-out workers at Exxon Mobil Corp have asked for a union removal vote. The National Labor Relations Board notified Exxon and the union that these workers submitted a petition to force a vote on removing the union on Wednesday. At least 30% of the members must now sign the petition for a vote for removal to take place.
