How bizarre that people are trashing this OP for trying to help other pilots !
If genuine; this OP is trying to offer advice, based on what they are experiencing on the inside of this airline. They themselves might be trapped and not able to leave right now - they might have children going through college, or a mortgage to pay off, or only a couple of years left before they retire. Hard to leave that and start again at the bottom maybe.
But they are trying to warn others about the current employment situation in this company, and some people are having a go at them for it ??
(I would however, suggest that the OP write directly to their union rather than ask their union for action via this website. Maybe they have tried that already.)
