Every single person I know either hated their Union because it does nothing positive for them except collect money. Or they hate it because it protects terrible workers from being fired and prevents any discipline. One of these people runs a 600 man electricians crew.
Anecdotal, I know, but the only people I know that like unions are bad employees the union is overpaying and protecting.
Example: heavy equipment operators Union goes on strike for more pay ( its already prevailing wage+++), all the other unions go on strike to show “support”, in the mean time they don’t get paid. 10 guys on my friends crew went two weeks without pay. They wanted to work and had no issue with the pay rate only the operators Union did.
