You completely missed the point, nonetheless you call people "deluded". It's one thing when the industry is just about picking up and taking some baby steps towards recovery and that recall is your one and only chance to get back into flying reasonably soon. Then, the decision is an obvious one, no matter what feelings are involved. Preserving and continuing your career is more important than playing it offended in hopes for something better some day. But, long-term, people's loyalty towards a specific employer does get influenced by disgraceful handling of redundancies and unprofessional, opportunistic behaviour. And, even if they have nothing better to choose at the time they get called back, they will in another year or two, once recovery has advanced enough to offer better alternatives. That's when the massive movement will start.
