Caynine...... as Keg said "AIPA can't go anywhere marketing itself for new members". It is an industrial law to do with poaching off other unions.
There is nothing to stop a group of people going to AIPA and asking how to be covered, AIPA would then be able to inform them on how to do so. It is slightly more complicated than joining a club and therefore if you and your mates are still interested, contact AIPA.
