No substantial bad factory conditions or request for higher pay, "just agree to collective bargaining agreements, that's all."
I was a welder back in NY in 1997, and joined a company and I was told by the Union's lackey that joining the union was voluntary. At the end of my three months, the thug came looking for dues. He clarified, "it's voluntary, you can take another job." Since then, the taste of a mobster mentality has steered me away from unions for the rest of my life. They once served a purpose, but my opinion is they have become less important and do not really do what they advertise.
The Swedish Trade Unions are dropping due to the ratio of native workers vs. immigrant workers, so it is a matter of time before the homogeneity of the population goes down, and trade unions with it. They're partially isolated from the EU, but too dependent to not suffer the coming collapse of the EU economies. Musk could just say FU to them too. With over 125,000 global employees, and a lot of countries subsidizing EVs to hide their real costs, the 170 Swedish laborers would quickly be out of a lot of work, and Sweden can buy other EVs and deal with them. The Tesla is most popular in Sweden, then Norway, and finally Denmark. The people who have already bought them would know who was responsible for them not being able to get their Tesla's fixed - not Elon, but their own government and unions. See how many other businesses get cold feet doing business in Scandinavia from this.
Maybe we'll see graveyards of Teslas in Scandinavia like we do of EVs due to failed startups in China. No win for anyone.
