Oh, how I smile when the corruption of corporate unions is exposed. This is what they are, inevitability and always.
If you think this is the exception, and not the rule you are in denial. Corporate unions and worker collective bargaining rights are not the same thing. Corporate unions hijacked workers’ voice and have used it for profit for 75 years. I am not opposed to collective bargaining - it can work. But it needs to be owned by workers, not corporate fat cats who profit from skimming workers’ wages.
I have dealt with a lot of unions who "represent" low wage workers, and at every one the union's employees have better wages, benefits, and working conditions than the people who pay for those things. It is a scam.
