It was a nice party. No one on either side of Management or the Union were influenced in anyway at the party or by the party.
Once (if) you gain some experience and lose some of your us-against-them angst, you'll realize that there is a time to flight for the contract, the polices, the grievances, the terminations, etc. and at the end of the day both Union and Management have a job to do.
Once that job is done, reasonable people on both sides recognize that we're all in this together, respect some of the people on either side and relationships grow out of mutual respect.
I've had shouting matches with Labor Relations over the years, there have been periods that we didn't even speak in passing, but a week or month later had lunch with them (we trade off on who buys).
It actually pays off to not hate each other. Of course that was the old Frontier. I have no idea how these relations will go with Ford & Harrison, BB and especially WH. I'm afraid my expectations are not high.
You get this experience from volunteering, working for the Union and the pilots or becoming an elected BoD member, not standing on the sidelines screaming when you have no knowledge or experience. Or even worse screaming when none of it affects you any longer.
