Why put money into them when it is all spent on things such as fighting other pilots in court to see which union has the biggest dick syndrome?
Unless all the unions in Australia work together, things will only go downhill. Look at all the good things that have happened to terms and conditions in the last couple of years with the AFAP, AIPA and JPC all trying to be the big player.
When they all get their ship in order, the backbone to really fix the problems in GA will be much better. Until then, only small issues will be fought.
