My understanding is the same as @
etflies. Unless you can provide language in a law that specifies other Seggy, the language is binding. As he said, it can be RENEGOTIATED at any time. However it cannot be changed willy nilly. Also, I worked for an ALPA carrier that gave our planes to another company, thus giving away our scope, for a "flow through" that involved more pilots on the seniority list than were previously covered. I did not approve of that. Others didn't as well (I can't say the majority didn't agree because I don't know and can't prove that). Why can't I prove that? Because our ALPA MEC have away the planes and scope without pilot ratification.
I can bitch and moan about ALPA. I watched my dues money go to lawyers to keep a captain on property after his 6th suspension by the company for different instances of negligence of company policy. Another pilot was kept on property after being identified as a person who stole property from an airport shop. Another captain was not only brought back, but was awarded higher paying equipment upon his return, after choking out a flight attendant. I will admit, y'all have some damn good lawyers. But I don't want to pay dues every paycheck to keep jackasses on the seniority list.
After that, I watched my dues money go to concessionary negotiations. I didn't hold high expectations of these negotiations. The company was in bankruptcy. I believe I held reasonable expectations for those negotiations. On the roadshows for the TA agreed upon by the MEC, reps were saying that this was the best deal we could get. I believed them. A couple of the reps "had seen the fleet plan" and it was good. Ok great. You guys were briefed by the folks involved, and are saying this is the best we can do to get a newer, larger fleet. They sold it. TA passed. One month later, BAM! LAX closes as a domicile. 5 months after that another domicile closes. Returning aircraft to lenders, with no aircraft purchases or fleet replacement. One year after the vote, still nothing. But my ALPA reps saw the plan and said it was good! Real winner there.
I don't hate unions. Unfortunately I feel that ALPA has become a business that is afraid of being sued. They can't possibly keep the best interests of mainline AND regional pilots in mind. It's physically impossible. "Well Mr. Mainline pilot, we promise more restrictive scope and pay raises." "Well Mr. Regional pilot, we promise you lots of bigger planes and more pay." Doesn't work.
My previous ALPA regional had no holiday pay, no min day guarantee, 50% deadhead pay, and had mid-upper level pay rates. Skywest, non union, has holiday pay, min day, 100% deadhead pay, and is a top paying regional.
Will Skywest's pay change, based on what the other ALPA regionals are agreeing too, probably. But I REALLY don't know. I don't know anyone that is involved with SAPA, and if I did they wouldn't tell me anything.
P.S. @
Seggy, the regionals that we were threatened might get additional flying if we don't vote this deal in: RAH and ExpressJet. NOT Skywest like you assume. If my memory serves right, those are two union regionals, one of them ALPA I believe

. And on the last vote when we were threatened the regionals of choice were PSA and Mesa. PSA voted yes, but you know this already. Again, two more unionized regionals.
