> "It's about the Swedish collective agreement model, and there is a consensus on it, both politically and between the parties in the labour market, Seko's president Gabriella Lavecchia told Reuters by email.
And yet this is not a legal obligation, as far as I understand, and Tesla is acting lawfully. So the model seems to be that there are unwritten rules and that the whole country is allowed to club you into submission if you don't follow them.
At this point it seems that at least some form of legal obligation (you give an example) would clarify what is understood to be compulsory... Transparent rule of law is also a model for a good reason.
From the outside it's a little odd (at least to me) that the Swedes seem adamant that Tesla must accept a collective agreement and also that there is no need to make that the law. That's the peculiarity, IMHO.
