I know people who stuck CFMEU stickers on their helmets simply to stop getting hassled by them onsite. A CFMEU guy told me off once for sitting on the ground COMPLETELY out of the way of everyone eating lunch (he was clearly letting me know who was in charge)...

There were stories onsite of bikies running "lotteries" and such too.

Also, if you weren't part of the union, you had trouble getting onto union sites.. it was total crap

I'm for Unions (and very left leaning).. But, my experience with the CFMEU showed they were nothing except abusive unless you kissed their arse. Also, to be clear, I'm not a business owner (and honestly, I got shit pay, which was part of the reason I left.. But even with shit pay, I STILL wouldn't join the CFMEU)

There are good unions out there. CFMEU however wasn't about being fair, they were just toxic bullies (many of which were clearly overcompensating)
