I'm not debating percentage, that's for the NC to do, but do we know how it's going to be distributed?

I figured we'd do it the tried and true way of - new rate, minus old rate, times hours worked during the duration -

Spirit did some longevity equation for their TA, and I hear others saying they want the same for us, is it truly fair? What am I missing? Isn't pay rate effectively a longevity marker? Admittedly, I'm on the lower half of the seniority list that's been here less than 5 years. But that's just it, half our seniority list is one extreme or the other. I know us junior guys don't want to get screwed either.
