Save yourself
Save yourself the frustration. If Prestige Jet already have the reputation of being harsh with their staff, why would you want to become involved with such an organisation?
This seems to be the "norm" throughout the Region regarding business aviation. "Work them hard, pay them low and if they are unhappy get rid of them". Oh yeah, don't forget the "Don't pay them" attitude.
Unfortunately, there will always be some Sad Sack out there willing to step in an take it. If all pilots were to boycott people like this they would soon be out of business. Another "pipe dream".
