Deauthorization of a union is much more difficult than forming a union in the first place. It is very difficult to obtain sufficient support for deauthorization without the union leadership hearing about it, at which point they can usually find sufficient reason to expel the member from the union. If there is an exclusive contract with the employer (which is usually the case in the US), this may result in the employee's termination.

Even if there is enough support for deauthorization to require an election, the NLRB has the authority to overturn the results of the election, and it has historically wielded this power quite generously in favor of the union.
