EAA/SSA - WTF?
United you stand to negotiate a decent EBA for all.
Divided? You'll screw each other.
Might be time to take a deep breath, a step back and have a good look at each other. Same people, same aircraft, same job, same pack of @rseholes you work for.
An outsiders perspective?
Pull your collective heads in.
Negotiate from the same plan.
Negotiate for the future of yourselves and those yet to join.
Anything else smacks of self-interest and ego.
