In this increasingly globalized world, each country is still different. You can't expect swedish workers to accept that you treat them like american workers just because your company is big.
I really like this part:
> Even postal workers will stop delivering mail to Tesla
Edit: deleting my comment. didn't add much value to the conversation.
The point of a union is to be able to push back on your employer, so that fighting for better conditions isn't a special privilege.
The entire point of a union is that you have enough collective agreement so that the company can't just fire everyone who pushes back. They can fire one person, or even many, but what if half of the workers are pushing back?
> also, mail workers don't "own" mail delivery.
They may not own it, but they do control it. Good luck getting your mail if every mail worker collectively decided to stop working.
