Flaps one.
While I believe your first statement to be true, I believe your second one should be the other way around.
If a new pilot wants to shaft him/herself by getting a TR then thats his/her problem. But if the pilots in the company dont do anything about it. That new pilot will take their job, for less and the Ts and Cs will never recover for that company pilot.
By penalising those pilots that buy type ratings and line training, you 'help' them to see that what they are doing erodes the members T's and C's. If a pilot has no union back up (which is essential insurance in todays market) and something goes wrong then maybe the majority might think twice before putting themselves in the same situation?
Ultimately, BALPA are there to look after those that support it. I think by banning pilots who pay outright for speculative TR's and line training could be a way forward. The question is, what can we do to stem the tide? It seems to me like the tide is just getting bigger!
