Not a fan of Tesla, but they’re not breaking any laws here.
There is an agreement between the employer organisation and the unions on how to deal with things in order to keep the government out of it. It’s called “The Swedish model”. This is what Tesla doesn’t want to sign up to.
IF Metall tried to get Tesla to the table to talk for five years, unsuccessfully, so here we are. Nobody wants the strike, but what can you do?
