I'm not so sure. The days of the Painters and Dockers have long gone.I can tell you that they're not chicken and are certainly not eggs.
They're very militant and very strong minded staunch unionists.
The likes you have never seen here in NZ
The Building unions are nowhere near what they were in the 80's.
I know someone at a big Union construction site employing about 60 men. Had a serious accident onsite, the second one this year. Union came in held a meeting, told the employer the site was closed until the Union deemed the site safe. The men refused to walk off the job, didn't support the Union, they went back to work at the employers asking and the Union Official skulked off.
Embarrassing. The Union has high wages and conditions as of right but there grip has slipped big time and when blokes don't back their Official the Employer can do as they like.
