Made the jump to Purple after almost 2 years at WN. Simply put - no regrets. Well, going back on first year pay kinda stunk but WB second year pay softened the blow. Honestly, I was more fatigued at WN than at FedEx. I"m a commuter and typically choose/build a hub-turn schedule for home schedule reasons and still find it easier on my 40-something year old body.
It's not perfect, but nowhere is gonna be. I think our hiring will stay steady for the time being as our retirements continue.
Best of luck in your future!
