If at least 30 percent of the workers in the bargaining unit sign the petition, then it must be sent to the NLRB's closest regional office, along with a cover sheet, NLRB Form 502. Once the petitions have been received and validated, the NLRB will set a date for the decertification election, usually about 60 days in the future. Individuals on both sides may campaign to sway the employees. When the vote is held, if a majority of the workers who participate favor decertifying the union, or if the vote results in a tie, then the NLRB will officially remove the union's recognition as the bargaining representative of the workers.
