Our website clearly states that we are not a union because, as yet, we are not. However, should we wish to become one in the future TULRCA is what we need to comply with, so we are.
Unfortunately for the PCCC you are going to have to grow your membership base from existing Cabin Crew only as the new Mixed Fleet Crew any entitlement to collective bargaining - effectively making it not worth the union subs as you are not going to get any benefit from joining.
Additionally as BA have promised that it will take years and years for MF to grow to any substantial size, you are never going to get any collective negotiating agreements as you will only be a small part of the workforce
