Technically I wasn’t defending their work, merely asking those insisting the NC be ‘thrown out’ if those people are willing to then step in to replace them. But since you bring it up, I will defend their work. The pilot group was polled and negotiated a deal that was acceptable by the criteria of the polling. But then the environment shifted due to other TAs. But I can certainly see why the NC would like to put this to a vote. Having already gone to the mat negotiating for the current TA proposal, it would be more effective and give the NC more leverage if this is now voted down. Then the NC can start fresh, relieved of compromises they have already made. It’s a clean slate of the old proposal gets shot down.
