Moonshot said it best.

My much less refined response:
It doesn't matter how "brave" your pilot group was, have up to date logbooks, a clean suit (red tie if its a Delta interview) and bring a positive attitude to the interviewers.. Nobody really cares what you were doing before as long as you left on good terms and kept your record mostly clean.

The union doesn't control or have any say in hiring.. That is the purview and responsibility of management.

Good luck, and don't use your vote to "send a message," thibk through the ramifications and the possible resuts 1-3 years from now. It doesn't matter to the managers.... This is purely a business/economic event, use your knowledge and to come to a thoughtful conclusion either in favor or against, and then prepare to continue your career goals.
