Yes getting the authorisation is important BUT is it even worth it anymore? With the RLA besides Eastern and UAL in the 1980-90s has ANY airline been allowed to (STRIKE) self help? I think the management of all airlines knows a strike will never happen because the RLA would drag out the process and never allow a strike to occur. Even a PEB with Biden himself yelling at pilots on the picket line to GET BACK TO WORK would show a strike would never happen.
I have an ALPA "battlestar". Skyway Airlines, strike, 1997!
The power in the strike isn't the strike itself, it's the uhhh, 'economic damage' and bookaways because the strike date is approaching. No one wins in a strike but because of a number of things that you can read about as it pertains to the Railway Labor Act, it's really the only tool we have as airline labor.
No one wants to strike, which is why you rattle sabers, get some media attention, get the attention of the traveling public and, hopefully, the board starts thinking "we're losing (or potentially losing) more money that we would spend to settle this contract"
Now the Europeans can get a bad crew meal and go on strike for a couple days, seemingly at the drop of a hat. That may be a better system to keep things from dragging on or it may not, I really haven't considered it.
To answer your question, for all that has to happen (or NOT happen) to lead up to a strike vote, yes, the people have spoken, it's worth it. Now if that result came back less than 90% in favor, the company is going to continue dragging it's feet or try to press for arbitration, which is bad.
