In some, I do honestly think they have just been shown what looks like a potential solution, and they are tired or in financial turmoil to the point of trusting the scorpion. Union leaders are people too, and even the "corrupt" ones still benefit from the entire workerbase being lifted up... basically its not the big draw to evil people like being a cop or politician is.
I don't know how best to solve this issue in the age of WFH and companies with massive regional presence, but, we need our unions to have faces, to have a hand to shake and a smiling face to speak with.
I've yet to see the Republicans do anything but undermine the workerbase's rights. Especially every policy under the first trump admin. Of course unions need leadership and of course any leadership will always be dogged by corruption. This reeks of a betrayal. The only thing the GOP can trade behind closed doors is to not go to the extremes they have against workers. That brings us back to the status quo which is nonnegotiable.
