It’s up to the companies and unions to handle.
When Tesla has refused that for 5 years + have a global policy to refuse, then they are not handling it, which makes companies and unions react.
To be clear: Companies in Sweden largely prefer this model over one governed by law.
Not relying on laws like this allows for more adaptability to local conditions or preferences, if the system allows this, while also having mechanisms for enforcement when a company has simply decided "we don't do business that way, and we don't care if that runs counter to the local norms".
It's not supposed to be nice. Swedish labour has understood a simple reality, you don't fight on your opponents terms. Elon Musk has a competitive advantage at hiring lawyers and buying politicians. So they pick the battle where they can actually win, collectively on the factory floor.
And just like tesla have the right to refuse signing, the people of sweden has the right to strike.
You went from calling this a bit “odd” and “a peculiarity” to “actually quite brutal” in the span of two comments. Jesus Christ the level of JAQing off in these Tesla threads from “the outside” (I wonder where) is insane.
It's simple. Above a certain size, you either get an agreement or no one will do business with you.
Put this way, it should tickle every libertarian mind. Free actors operating in an open market.
The level of reactions against Tesla does not make the system look 'nicer' than others: Maybe effective but actually quite brutal.
