The Swedish Transport Workers’ Union will no longer collect waste from Swedish Tesla workshops starting December 24, in an attempt to persuade the carmaker to accept a new collective bargaining agreement with the Swedish union IF Metall.

According to Reuters, Tesla has been facing a backlash in the Nordic region from pension funds and labor unions, over the company’s refusal to accept a collective bargaining agreement for Swedish mechanics that covers wages and other benefits.

As a show of solidarity with the mechanics, dockworkers, drivers, electricians, cleaners and postal workers in the region are refusing to provide Tesla with their services.

"This type of sympathy action is very rare. We are using it now to protect the Swedish collective agreements and the safety of the Swedish labor market model," said Tommy Wreeth, president of the Swedish Transport Workers' Union, in a statement. "Tesla can't ignore the norm on the Swedish labor market.”

Tesla did not immediately respond to a request for comment from Reuters.

The union's December 13 announcement comes on the same day that a Swedish court of appeals said it would overturn a ruling that previously allowed Tesla to collect license plates directly from manufacturers so that the company could circumvent Swedish postal workers attempting to block license plate deliveries. That case will now be sent back down to a lower court for renewed examination.
