Swedish unions don’t work like that. You don’t form a new union at a company, you just join an existing union. In this case, the striking union is IF Metall. They represent mechanics (and other metal workers but that’s less relevant for Tesla). What someone working in HR, sales, marketing or IT support at Tesla thinks about the strike is completely irrelevant. Metall is representing its members, and those would in this case be mechanics. Other employees of Tesla don’t matter to this strike.
