Wounded Duck,
And how do you KNOW that if you pick up a 15 hour trip as a line holder you won't get paid 15 additional hours? Seems like you are reading tea leaves and coming to a conclusion that might very well be incorrect.
I doubt VERY much the union would vote unanimously to approve an agreement that cuts lineholders ability to get paid from open time.
I think you need to wait for language and Q&A before you make such sweeping assumptions.
And I do not see a 2022 COLA increase as a contract extension. The contract becomes amendable on the same date as previously, and negotiations will begin. There is nothing in section 6 or precedent that says X many months from last COLA.
