Sorry, I didn't see the second link. OK, it sounds like a bunch of accusations were made, some were dismissed, and there will be a hearing on the rest. Not having seen any of the evidence, I don't know if they're true (just as you don't). If they are, then they should be punished in whatever way the law provides. That doesn't change anything about my initial point that this plant, and these jobs, exist in large part because of Alabama's favorably pro-business labor laws.
"Polite? No, you're parsing out acceptable tactics of workplace intimidation based on nothing more than the very lax and pro-employer labor laws we have in this country. "
If you mean that I won't condemn a company on this issue when it doesn't act illegally, you're correct.
"A nice euphemism for firing people for talking about unions, aka acceptable intimidation."
No, that would be illegal. If it were up to me, I would change that, but it's the law at the moment, so I don't consider it acceptable intimidation.
Acceptable intimidation would include, for example, pointing out to workers in a non-specific way unionization would threaten the health of the plant, and might lead to reduced jobs or benefits.
