It works because Sweden culturally values social consensus much more than we do in the middle part of Europe (lived in Germany, Sweden, Belgium*, UK for a decade each [*Belgium not quite as long]).

Germany has different, more restrictive rules, around sympathy strikes than Sweden - so … you can’t compare the two countries on what workers legally can do and can’t.

State agencies have to seek the best offer for their contracts ever so often. They bulk deliver via one company that needs to win a bidding against other companies. Usually that means a company that signs a contract with a state agency trades some profits for the prime service contractor. The contract IS a business contract. But the state agency itself is bound by administrative requirements to get the best deal they can, whenever a previous time-based contract with a company has run out. Either side would be in breach of contract: PostNord if they’d stop delivering (they don’t - PostNord workers use their legally guaranteed right to strike); the agency if they’d suddenly breach the exclusive bulk postage contract they negotiated.

I don’t think US state agencies operate that differently on that end? The difference is that workers in Sweden have rights that US workers don’t.

Yes, but obviously the agency would stop being politically neutral about the strike if they’d treat Tesla different than other companies, in theory. They obviously don’t want to start to make exemptions to their administrative structures on the demands of a company.

Given that no other company (other than Toys’r’us) did what Tesla did there’s no previous case to compare it, to. So - this will go through the courts.
