I see your perspective, but in their “win” they cut off their noses to spite their thuglike faces.
Only if you assume that the plant would have unionized. IMHO the union’s demand/ultimatum for unfettered access to organize us a good indicator that the plant probably wouldn’t.
Iow those workers were probably never going to unionize anyway. So the union didn’t lose anything in that regard. What it gained was a better appreciation, particularly by the political class (who wanted the jobs, regardless of whether they were unionized or not), that it can be dangerous and is a powerful force to be reckoned with.
