Yeah, you’re at least the second person who’s come into the thread whose claims about how unions should work are fundamentally at odds with how unions do work, and indeed how unions must work if they’re to have real power.
There’s a name for a strike that’s polite and doesn’t disrupt an employer’s business: a failed strike.
It’s difficult to discuss this particular labor action when there’s such widespread misapprehension of labor actions in general. It’s as if someone comes into a thread on California’s best sushi restaurants to declare that fish shouldn’t be eaten raw. How do you respond to their posts without a general discussion of food safety?
But I do agree that inasmuch as explaining why your objections are without merit requires explaining how strikes work, it may not be possible to offer such an explanation here.
