Under current NMB rules, it is impossible to decertify a union because there is no official mechanism to do so - and that is straight from the NMB.
If a union is already representing an employee group there is an unofficial workaround. Another organization or individual indicates their desire to become the bargaining agent by submitting an "Application for Investigation of Representational Dispute" along with a sufficient number of authorization cards signed by members of the employee group (which is what USAPA did to have an election and replace ALPA). If the new organization or individual wins the election, they can then voluntarily surrender their authority to represent the employee group and the group becomes unrepresented. In other words, a "strawman" opponent to the incumbent union is used to get a representational election and if the "strawman" wins it relinquished it's role as CBA.

Decertification
Decertification is the loss of its NMB certification (representation rights) by an incumbent union or individual. The NMB does not have a union-decertification process per se. However, if less than a majority of eligible voters votes in favor of representation, the NMB issues a dismissal, and the incumbent organization or individual loses its representation status. In determining whether a majority of employees voted, all votes for representation are totaled.

Decertification.
There is no express provision in the Railway Labor Act for decertification
of a certified representative. Although, the Mediation Board once took the view that the
Act favors the organization of employees, and would not entertain decertification
petitions, this position was struck down by the Fifth Circuit on the grounds that the Act
also protects employee freedom of choice. Russell v. NMB, 714 F.2d 1332 (5th Cir.
1983), cert. denied, 467 U.S. 1204 (1984). See also In re Chamber of Commerce,
14 N.M.B. 347 (1987).
Historically, RLA employees have pursued decertification by means of a
straw-man election, a proceeding in which an employee or group seeks certification as a
new representative solely for the purpose of ousting the incumbent. Once certified by the
Board, the new representative disclaims his status and the employees are then
unrepresented.
In Atchison, T. & S.F. Ry., 8 N.M.B. 469 (1981), the Board refused to
process a “straw-man†application. The Fifth Circuit subsequently ordered the Board to
process the application, stating:
The Act supports but does not require collective
bargaining, and in our view, the implicit message
throughout the Act is that the “complete independence†of
the employees necessarily includes the right to reject
collective representation.
