Tesla has no manufacturing plant in Sweden but its electric cars are serviced at workshops across the country, where around 130 mechanics affiliated with Swedish union IF Metall began a strike on Oct. 27.
They were soon joined by dockworkers and car dealerships who refused to handle Tesla products.
About 50 unionised workers at Hydro Extrusions, a subsidiary of Norwegian aluminium and energy company Hydro (NHY.OL), will stop work on Tesla car products next Friday, a spokesperson for the company said. The rest of the plant, located in the city of Vetlanda, will keep running, the spokesperson added.
Hydro Extrusions's Vetlanda plant makes aluminium profiles - aluminium alloys transformed into shapes, and is the first Tesla supplier in Sweden to down tools in support of the mechanics' strike.
Tesla did not immediately respond to a request for comment.
The carmaker told IF Metall on Nov. 6 it did not want to sign a collective agreement, the union said.
"We want Tesla Sweden to sign a collective agreement... We want this conflict to be as brief and short as possible," IF Metall spokesperson Jesper Pettersson said.
German unions have pressured the carmaker to implement a similar agreement for its 11,000 workers in Gruenheide, near Berlin.
