There won't be any shortage of instructors. As I previously mentioned they can force the flexes to train their replacements. I know you are thinking that no line guys would apply for the job and you might be right. The fact of the matter is they would not need to. Management could just say "since none of you line guys want to instruct we will hire all professionals". The company uses the flexes for 6 months to train the new professionals and walah, problem solved. I know that the contract requires all PC, PT's and checkrides to be given by line guys but I'm pretty sure they will find enough guys to stick around to conduct those rides.
The company would love to go to all professionals. It would save them a bunch of money and would just add fuel to the fire of being overmanned.

It is interesting how you want the flexes to show solidarity by quiting because you percieve it would help your cause, but where were you when they got hosed in the section 11 negotiations. The fact of the matter is that the flexes and anyone going thru training or anyone that gets a reserve line is getting hosed by having to work the same number of days for less pay. Where as a line holder is getting less pay but at least they are getting more time off.

Most flexes work very hard to provide you with a smooth, productive, stress free training experience every time you come to the school house. If you think about the consequences of all the flexes quiting and the alternatives that the company could employ. YOU REALLY DON'T WANT THE FLEXES TO QUIT.
I know that when I go thru training I want the best insructor, and the best communicator that can explain things in an easy to understand and easy to remember manner. Not everyone has that skill or capability.
