A carefully co-ordinated plan of civil disobedience could kill off this whole ASIC bullsh!t.
If every pilot and LAME returned their ASIC card and rocked up for work carrying their licence and another photographic means of identification (preferably a passport, but a driver’s licence should suffice) what might be the outcome? This would not be industrial action, as the staff have reported for work as rostered. It would be up to security to deny airside access or round up and detain those who slipped through their net. The authorities would be busy for a day. The jails would be overwhelmed with those who security did not pick up before they went airside. Or, if everyone simply declared at security they had no ASIC, everyone would be turned back. Peacefully.
Such action would inconvenience the public for a while, and cost the airlines millions, so government would have to roll over in the national interest. They would adopt emergency measures within 48 hours for appropriate licences to be recognised as sufficient, if backed up by photo i.d. Then they would adopt a fit and proper person test (as the Kiwis do) for issue of licences. This would be good forever unless some criminal conviction followed.
Jobs for security snouts would still be safe as they would be able to pay more attention to non licensed lurkers and maybe run some patrols around the perimeter fence looking for Little Rocket Man.
