Q: Will I have the opportunity to vote on whether or not I am represented by the Association?
A: Yes.
Following the completion of the American ? US Airways' merger, the Associations will file representation applications with the National Mediation Board (NMB), a federal agency, which will culminate in three separate elections, one for each of the Mechanic & Related, Fleet Service and Stores classifications. You will vote in the election of the classification in which you work with others from both carriers.
LIARS! And they are still blindly followed by some. Our pension is safe, they said so!
