I'm a yes vote.
I'm not on probation, nor was I swayed by the (rather awful) presentations by the RJ or the company trying to sell it—if anything, they made me less inclined to vote for it.
However, let's get a few things clear: it's not "concessionary" (do you realize how insane that sounds?), nor is it a "pay cut."
Not everyone is at a regional just as a stepping stone to a major, despite the commonly-repeated statements to the contrary. I'm happy here—I fly with great people, on a plane I enjoy, and I experience -excellent- QOL. Am I paid fairly? No, of course not. Does the pay package fix that? No. However, the economic situation of the regional industry is quite complex, and my evaluation of the situation led me to believe that the pay package was relatively fair, all things considered; should the company have any trouble attracting or retaining pilots—that is, should we have any actual leverage—I have no doubt they'll be the first party wanting to come back to the table... at which point we can re-examine the situation.
