I was union for 12 years, joined when I got hired because they were fresh off of a strike and got a good contract, and the guy who vouched for me was union, it was the right thing to do. The union was a shit show, the company was a shit show. I pissed off both camps
Eventually the shitty union leadership left and I took the job so another dipshit democrat lifer couldn't.
They tried to fire good people for petty shit, got one. I had to get my pound of flesh, and I did. Eventually we could end a termination hearing by meeting up with the boss outside
"If you want to give him 3 days off for being a dumbshit, I won't fight it, 4 and we have a problem"
The clout I had I used to make things better, procedures, safety stuff , rescue team, got more tooling, then turned around and made sure my guys respected the new equipment.
Went to big table negotiations and both sides were unreasonable, the company wanted to break the union, the head union guy wanted to retire with a big win, we got pushed into a strike and walked right into it.
I was pissed.
But, the union did way more for me than I'd ever expected, paid my rent for like 18 months, way more than I'd ever paid in.
They folded at some point, but are still working the "case" through the nlrb.
Fuck all public unions.
In unsafe industries, being able to tell a retard boss to shove his big ideas up his ass is pretty choice.
In general, if a company is unionized, in going to assume it's because it's poorly managed, and I don't really want to be employed there hourly or salary
That's my take
