Tesla and IF Metall do not agree on collective agreements. As a sympathy measure, the Transport Union therefore put a Tesla blockade on all Swedish ports on Tuesday.

The Port of Södertälje receives up to 500 cars from Tesla a week. But when the boat arrived during the day, there was not a single car from the American company.

"It shows that the blockade is already working," said Tommy Wreeth, president of the association.

Transport suspects cheating

Transport suspects that the American multibillion-dollar company, founded by Elon Musk, is trying to take other routes into the country.

"We are looking at what we can do to prevent them by land as well.

They are also in contact with the Nordic trade unions to find out if Tesla ships more cars there and then try to drive the road across the border.

We've reached out to Tesla for comment. To TT, the company says:

"It is unfortunate that IF Metall has taken these measures. Tesla complies with Swedish labour market rules, but like many other companies, has chosen not to enter into collective agreements. We already offer equivalent or better agreements than those subject to collective bargaining and see no reason to sign any other agreement."
