I am under the impression that they did not strike due to fear of reprisals from Tesla. Therefore, an adjacent union striking against Tesla can be a substitute because Tesla doesn't have leverage to threaten them. It's worker solidarity.
So you think the workers who didn't join the walkout are lying when they say they fear the union and who they actually fear is Tesla? Do you have even a shred of evidence for this claim?
Is it laughable though? The union is blockading shipments to a company that chooses not to join. The next step, apparently, will be an embargo on the company's electrical repair work and trash service.
Seems like extortion to me, so I certainly wouldn't want to put my career or my family in the crosshairs of a group that's willing to sink to such lows.
When the mafia demands protection money, it's prudent to fly under the radar.
When a corporation arbitrary decides not to do business with an individual, it's just their legal right.
When individuals decide not to do business with a corporation, it's a mafia, huh?
Corporations have to be forced to submit to society or they'll run roughshod over everyone as soon as they are able. They might even play nice at first, offering good conditions and pay, but that would never last. Learn from history.
The whole point is that it's not considered a restraint on free trade if two businesses can't agree on a price and thus don't conduct business, but somehow becomes one when one side is the employee.
