Please think carefully
I understand emotions are running high at the moment, however I would just like to point out the following;
Belonging to a union is not just about the unions ability to conduct IR. It is also an insurance policy for yourself.
Consider carefully before leaving a recognised national union for a consultative committee(cc), what would happen if you were injured at work. Would the cc have legal nouse to help you out? If you were unfairly dismissed would a cc be able to offer you full legal support?
Having worked for an airline on which I was part of a cc, some good things came from it, however we eventually went over to a unionised labour force purely for the other options it gave us.
