First off, I find the younger pilots to be more engaged and knowledgeable. Secondly, contracts don't expire, the become amendable.
So my question to you is how many Local Council Meetings, Joint Council Meetings, or other ALPA sponsored meetings have you attended? Do you engage your reps? Volunteer?
I understand we are all busy with our lives, but if you don't get involved at all, who will? You are ALPA. That all there is to it. If you don't like what ALPA is saying on your behalf, fight to change it.
