Your kidding right?
Closed door meetings, threats of closures, mailings to the house, if management has nothing to do with the election then why are they involved in the process, they have to submit names, address and signatures to the NMB, they inflate the lists all the time.
That is why they spend millions to fight a union being elected to represent the employees, right? Cause they are not involved, lol.
You really need to educate yourself, cause apparently you have no idea.
Read a book called "confessions of a union buster" by Mary Levit, you will see how much a company is involved and to what lengths they go to to stop unions.
And an election under the RLA is not a simple majority it has to be 50%+1 of all total eligble voters, not just a simple majority.
