Because almost all workers in Sweden are part of unions, those unions often work with the other unions and sympathy strike. Which means that they will not work with the company the unions are striking against.

This is so that the companies cannot bypass the strikes, which is often the case in other countries without as strong unions as Sweden does.

Elon would just respond to that with claims that Sweden is a Nazi country and suggest that Putin needs to invade for the good of the world

Bad title, they’re just doing what is required by law.
