Very sad to see and read. Talk of pilot bans etc mean nothing.management don't care if a pilot is on a ban list long as they are signing up (which they will) and planes are taking off. They are eating you from the inside out.
If every jetstar pilot however said next friday etc we are all not working no matter what, then it would cease straight away. No planes taking off, then it would be taken very very seriously. the ball is firmly up to you guys. Good luck.
