I'm sorry, I wrote about a thousand words in response to your question but then realised that the issue I wanted BALPAs stance on was so deeply intertwined with other issues that its difficult to explain, even to myself.
After typing and typing I reached my own conclusion and that was that this actually has **** all to do with BALPA. BALPA is taken in whatever direction it's members want. If there is no BALPA movement on a subject that's probably because there's no pilot workforce movement on that subject.
Hence, all the problems to do with recruitment and training demands (SSTRs, pay to fly) placed on the wannabe actually come about because pilots who are union members are either too blind, lazy or selfish to do anything about it. Why should they care, they'll have moved on by then. The issue isn't BALPA, it's human nature. Something I'm not gonna bother changing.
So I'll shut up here.
