There was a time when everyone was at the bottom. maybe at the bottom when the Asian Financial crisis struck in 1997, or just above the bottom after 9/11, perhaps barely above the Bottom post 49ers when SARS hit in 2003.
I've had opportunity to leave, I had seniority which influenced my decisions. I knew the rules of the game and everyone who plays knows too. It is best to keep the rules of Seniority based redundancy in the contract. Last in first out. Sometimes those rules hinder our opportunities and prevent us from leaving for the companies benefit, and other times it protects those who stayed on. Wanting to change the rules because you don't like them is shortsighted at best.
