So when is the MEC going to fire the Negotiating Commitee ? Or are you willing to recall MEC members ?
Are you willing to wait out another TA for an unknown period of time for a better TA ? That answer could be ABSOLUTELY yes but understand that there is a price of time and money (lost earnings) for another bite at the apple.
If the mediator thinks this was a good deal (whether it is or not is immaterial) game over and be put on ice.
I have supported this pilot group either way and always will - just trying to paint the bigger picture.
Good Luck
