I like unions. But the CFMEU, as I understand it (which is 30% at best), is a corrupt and criminally associated union.

Anecdotally, members of the CFMEU have always been the worst kind of people to be in a public space with. The few acquaintances I have in the union are racist, sexist, and generally unpleasant.

So ultimately while I think the government should keep off, the CFMEU is not an organisation I'd personally rally around - owing to internal culture and criminal/gang associations.
