We had nearly the same at XJT. Here is my theory... 5% are brainwashed new hires who are just off probation. 5% are guys who know they are leaving asap and want a few extra dollars before leaving, and 5% are guys who are trapped and are never leaving the regional level and want negotiations to be over so they can get their few extra dollars. Add in a smattering of schoolhouse guys who hardly ever fly the line. There are your "YES" vote demographics. Very small groups of guys with slightly differing opinions, but voted in favor.
