Sweden doesn’t have laws that set working conditions, such as a minimum wage. Instead these rules are dictated by collective agreements, a type of contract that defines the benefits employees are entitled to, such as wages and working hours. For five years, industrial workers’ union IF Metall, which represents Tesla mechanics, has been trying to persuade the company to sign a collective agreement. When Tesla refused, the mechanics decided to strike at the end of October. Then they asked fellow Swedish unions to join them.
