This whole AIP thing is a kick in the nuts. Has anyone ever heard of this, in any contract? Yeah, I have heard of an AIP, but then taking months to turn it into a TA? No, every other negotiation ended in a TA immediately. We are being played boys and girls. AGAIN.......
My guess? It won't pass and the MEC knows it. The NMB already gave them an unofficial "NO" to both requests for a release to 30 day cooling off, at least until after the presidential election. After the election, the lame duck pres (lame duck for 2 months or 4 years, depending on whether he wins or loses) might then release us.
This whole thing smells bad, and I would guess it is just a delaying tactic.
