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.
