AIPA's warning was nothing more than an attempt to destabilise and undermine the PIA about to take place this weekend, for whatever reason. Slater and Gordon have provided an indepedant ruling in favour of the AFAP.
Firstly, this whole issue really is an irrelevant distraction. How many AIPA JQ members actually joined AFAP in the time since the vote? Given AFAP already have 80% coverage, some pilots are in the TWU and many would have no representation at all, the amount jumping ship in this narrow timeframe would be two tenths of fu€k all.
Even if the warning is heeded it would have zero effect on the success of the PIA.
Secondly, lawyers don’t provide ‘an indepedant ruling‘, they provide their opinion. If you want a ruling, ignore the advice, get disciplined by Jetstar and then take your defence to the FWC or court, then you can get your independent ruling.
