Please read paragraph 5 of the protocol language a couple of times. It is a separate issue regarding mediation. Paragraph 4 states they are to use mediation to get to a T/A. Paragraph 5 detail what will happen if it fails. They "may" not of intended for it to read that way but is says they will use mediation before arbitration. That language should not be contained in that paragraph if that was not the intent. Sloppy work. Also, note that the APFA president confirmed the language at a Miami roadshow. She also stated she would be pushing for it. So, again, might not be their intent but that is what it reads. Even the union would be smart to argue this point. Why would they ignore it? It is there, so utilize it. Any good attorney worth anything certainly would. This is a missed opportunity otherwise. Roll over and play dead I guess.
Not trying to argue with you but pointing out this is a legal document. Said legal document has provision for mediation in the section that defines steps of what to do if T/A fails. This is where poorly worded document can actually benefit the flight attendant group, so roll with it.
