You can theorize that was the reason, more time to "beat up on the reps", but but that doesn't provide any evidence.
Per the Delta MEC Policy Manual, the reps are required to have any TA for at least seven days unless the MEC votes to waive that provision (they didn't). Also, discussion is amongst the reps, no one else has speaking rights unless it is to answer a reps questions. The Chairman functions as a moderator, keeping a speakers list, and to have SME's available to the reps to answer detailed inquiries or to explain a provision when there are questions. It is the Reps, not the admin who control the process once an agreement is in front of them. I still can't find the part where 16 (the MEM reps were supposedly given speaking rights even though they had technically lost their LEC the month prior, but they had given direction and redirection for the entire process and had a pretty legit claim to being involved in the deliberations even in their vote didn't count according to the by-laws) of our peer elected representative were fooled so badly or beat up on so hard that they "fell in line" so willingly. Please show me some concrete evidence that somehow 5 out of the 14 voting reps (or two others) didn't fall for the ruse. I don't believe that our peers are that gullible or foolish. Those reps made a very difficult call, and the pilot group agreed with it nearly 2:1.
I don't think that thousands of supposedly intelligent pilots and their deeply involved representatives are fooled that easily, I guess others do believe that.
