To some, holidays off is a very real QOL item, and it's worth talking about in negotiations. In my category, it's mostly ultra senior guys getting GS over holidays anyway. Why not just have it hashed out in the PBS process? I love me a GS here and there as well, but I'd much rather have holiday pay so the guys who want to fly will bid it. Then guys who want to be home, get stability in knowing they'll be home.
Just saying wait a bit longer is along the lines of, "well I had to deal with it, so you should too"...it doesn't have to be this way. We're all professionals who've paid plenty of dues at the regionals or in the military. Being junior can be terrible enough, there is no reason to not try and make it just a bit better.
It's funny to me that we have guys that are of the mindset of protect the GS system at all costs. I'm all for keeping the current GS system in place. But to intentionally NOT go for QOL items in our PWA so they'll continue to get GS's is not only self serving, but also an extremely short sighted way of looking at things.
