How does this case differ then?
Only in that I very much doubt QANTAS, Virgin, Jetstar would forward a rejection to an applicant that read....
"The fact that a professional pilot has threatened to sue us instead of taking a graceful retirement from a flying role is noted and will be passed on at CEO level to all HR heads at major Australian operators therefore black banning you from Australian Aviation. Your Call
Have a great Day"
A "professional" (using their words) Airline Company would send a less condescending and threatening NO THANKS reply. So it is not about why panic not getting hired, it is about the reply that was sent.
Anyway, good for you and those that support this kind of behaviour, just that I, and a I would suggest a good percentage of decent people don't.
