Shit man, on an ideologic level I agree with what you said.
On a humanistic level, these guys aren’t perfect, and what they are saying is probably very emotionally driven right now. It’s not supportive to the unionization cause to hate on them at the moment; support them in the short term, and reflect/educate on their conduct in the longer-term.
If job candidates are suing because they believe a company is being particularly inappropriate, that is at direct cost to the candidate who 99/100 times has less resources than a company. And they will be snuffed out in court in a jury trial if they are clowning around with the legal system.
The company will also pay, but in that same 99/100 times the company will have more resources to fight in court in most states. It’s in the best interests of communities, culture, and the people’s right to force the legal battle upwards instead of downwards
