It's not crazy when you understand the Swedish model: labour laws are minimal, setting just a very basic framework which is then taken to employers + employees negotiations to set the other terms of employment for an industry, in that it's a pretty free labour market. The counterpoint is that it's required that employers and employees collaborate to set the minimum arrangements for employment.
Tesla is refusing to abide by this model, in the Swedish model sympathy strikes are legal since that's one way that employees from other industries can support other workers in their struggles, the employees of PostNord decided to take sympathy action against Tesla for what they consider an attack to the whole model of employment and labour in the nation.
What is crazy is a company trying to subjugate a whole nation's system of employment for their own benefit, for that Tesla is being collectively punished by workers in other industries for trying to undermine the labour market as a whole.
