Answer - C - In the case of a decertification election, 30% of employees must sign a petition asking for a vote.

Key Takeaway: If an employee so chooses, they can petition the NLRB to decertify the union. In this case, the employee would have to provide evidence that at least 30% of the union supports the decertification. This event can also occur if a given employer gains evidence that the union no longer has the support of a majority of the bargaining unit.
