Sorry to interject on a company specific thread ( I drive the 737 for another low cost operator), however I have a little experience of Globespan and just wanted to wish you the very best of luck.
Secondly, we have just emerged from a period of balloting over industrial action at the company I work for and I have to say that if you are looking for support from BALPA, then don't expect too much. Many of us too are joining the IPA, myself amongst them, however most impressive of all were the TGWU.
I was suspicious that they wouldn't be keen to assist a profession that the public may consider overpaid and elitist, however that did not seem to be the case at all. Naturally they do not have the specialists in aviation law that BALPA have, but they seemed genuinely keen, and certainly able to buy the best legal advice as necessary. As I say, for all their expertise, BALPA were as much use as chocolate ailerons.
Just a thought, and as I say good luck.
Cheers,
MoT
