Norwegian's largest trade union Fellesforbundet has said it will block shipments of Tesla cars meant for the Swedish market starting on December 20th, as a way to support striking mechanics in Sweden. Swedish unions have been on strike against Tesla since October to try to force the company to sign collective bargaining agreements for its mechanics in Sweden. Tesla's policy is not to agree to collective bargaining and that its employees have equal or better terms than unions are demanding. However, Nordic unions say Tesla should play by the typical norms in these countries.
