The Australian union movement has lost relevancy, hence it's rapidly dwindling membership. Neverthless they wield a disproportionate amount of power thanks to the aparatchiks who have wormed their way into the ALP we see today.
Said it before and I'll say it again; the ALP started on its slippery slope to irrelevancy when Goof took over.
And yes, I would love to see a return of the Dockers.
Bunch of thugs and crooks, them and the BLF. But at least they didn't pretend to be anything else.
