"Pilots traditionally pay for the cost of endorsement training, which Jetstar contracts out" How many years does it take to make a tradition? Jetstar haven't been around long enough to have any.
"Jetstar (included that it) requested he take leave during his training period" Training should be done over one continuous period. On each flight the pilot consolidates and improves over the last. This is why it takes less hours to get a license when you do your training all at once in a consolidated course rather that ad hoc with a flying club.
Six different Training Captains, please. Whilst each Training Captain is reading from the same book, each has his own interpretation and ideas, not to mention personality, another contentious issue with this case. Not everything is covered by the manual or SOPs. For a pilot to have the best chance, his line training should be undertaken by one and only one Training Captain, anything else is substandard.
A very dangerous precedent is being set here. The Jetstar Pilot Union should take a stand against the company and fight for the right of the pilot to have the proper, continuous training that everyone deserves. It is too late for this pilot, Jetstar should just accept the cost. They charged this guy for an interview and pre-employment testing which he passed. He completed an endorsement successfully. They failed him when they failed to provide him with proper training. No one can say what would have happened if he was treated differently, fairly. His life has already been pulled apart, don't make him pay for the shortcomings of Jetstar.
