"I trust the negotiating committee"
This is the exact wrong mentality and it is one that pervades amongst this body. It is a Top down thinking and directives where we'll tell you what's best for you and you'll like it. Be real concerned when people who think like this park themselves in positions to make decisions for you. That's the kind of hubris that allows them to "negotiate" terms of a significant section of the CBA outside of section 6. Then add leading survey questions to gain endorsement of the same repackaged garbage. If there's mistrust it is well earned. Anyone who's good with trusting that process or those players is not someone I'm gonna spend one moment listening to and neither should you.
Voting down a TA isn't some kind of uninformed gamesmanship. It is a reaction to a process driven by the forementioned methodology. It is the only opportunity the rank and file has to resoundingly reject that mindset and clearly communicate that it is unacceptable.
We need to reimagine what is possible. Stop being willing to limit your expectations because someone says the NMB will think unfavorably if our desires seem (to them) unreasonable. If someone can tell you what a mediator will think or do in the future they're clearly wasting their talents flying airplanes.
