In Sweden, the union can blockade a company that they are "negotiating" with. That means that all other unions will refuse to work with that company, and this goes for both suppliers and customers of the blockaded company. No more transportation services, buying parts, getting service people to show up when your equipment is broken, delivering your goods to customers, etc. So, being blockaded is a risk which should be known going in.
