IMO, when Delta got their TA and Kirby announced publicly they wouldn't respond to our negotiations until he saw if that passed or failed, that was the day our MEC should have filed for mediation.
It doesn't matter if theirs passed or failed, if it passed, that was the floor, if it failed, the floor was going to be higher. (It would have been a deal for Kirby to settle then)
Now here we are, "Couple weeks Kirby" wasting more and more time... They weren't serious before and they aren't serious now. Sure, progress is being made, but when do you wanna call a spade a spade?
