At a minimum, this would mean that unions should not be recognized without a secret-ballot election of the workers. “Card check,” in which a union is recognized as the collective bargaining representative when it simply collects signatures from a majority of employees in a bargaining unit, is an unreliable method for measuring worker support and is vulnerable to abuse.[50] Workers’ right to remove a union that has lost majority support should remain as well.
