You are not arguing the contract, like you have no argument against them.
You can't argue with them. They don't understand.
Socks have been proposed to be put into the contract for years. Even when Carey was GP. Everything comes at a cost nothing is free. People need to understand it isn't just one pair of socks for one person one time. It's thousands of pairs for thousands of drivers to be replaced thousands of times. If that is negotiated into the CBA it comes at a cost. What would they be willing to give up? Nothing.
Their old argument and comment is record profits. They also fail to realize 4 billion a year sounds like a lot of money but for a global company in the grand scheme of things it really isn't.
So when you say I have no argument against them I disagree with you. I choose not to argue with them because it's pointless. If they had a clue about negotiations then we could debate. Their goal is only to pound the current administration no matter what.
