When you get rid of people you tend to try and get rid of the very top (buy outs for those near retirement) and the very bottom, via seniority I suppose. If you did seniority only some places would be royally screwed, for instance what if they either had all senior people stay and then retire and then their junior people get Rif'd. But no one here has a crystal ball. I have 18 years in, I am top 5 seniority, and I think I'm safe, but you never know. Though I'd take an early retirement in a heartbeat if they offered me 39% of my high 3 at 18 years now, instead of staying the 25 I need to to be eligible. Won't happen, but it is my dream.
