I don't think there's hard feelings and resentment towards the people who are senior, as that's a way of life in an airline job. I think the hard feelings and resentment stem from the union making a decision/resolution without the majority supporting it. Posting results from some bogus poll, where ALL of the union members did not get to vote is crap.
There is a significant amount of negative sentiment regarding our MEC in the crewforce right now and this is just another log on the fire.
