Zippy you are right
I don't say each one acts on his own. That is exactly what you don't have to do. That is why unionizing is necessary.
I say you all use your phone, call your BALPA representants, and tell them what you feel, what you want, what your worries are.
Even better: Visit them, a few of you at the same time. And then visit them again, and call them, too. I am sure you all would be amazed at how quickly things would start changing.
They are not the general of an army nor you the following orders soldiers. You must take part in the strategy if you feel so. Having representants doesn't mean that you forget about the issues. Your problems are yours, and BALPA is one of the tools you have to solve them. Use that tool. It never works well on its own.
Let them know how worried you all are (if you are). Don't blame them. It is your fault, too. You have to communicate well. That's all. Not easy, however.
