I remember one smart-arsed union 'ban' by the BLF [Builders Labourers Federation] that halted a 'continuous' concrete pour...[naturally] half-way through it's progress, destroying the success/integrity of a multi-storey construction....and a further 200 concrete trucks in 'convoy' that had to have their loads dumped.
Put simply it was economic terrorism/extortion.
Ultimately the BLF was de-registered...so they sent their goons up to Sydney to muscle in on the MWU.... but at least one came back with 2 broken arms....clearly the goons in Sydney were bigger than the goons in Melbourne.
On the other hand...Little Johnny Howard [our PM] thinks he has a mandate to wipe a 100 years of unionism history from Oz and drag us screaming back into 19th Century England, slaves and all...
Both sides are equally contemptible, more often than not....
