How Sweden's Longest Strike Ended: Tesla Bought Out Every Striker and Never Signed a Union Contract

Tesla never signed a collective bargaining agreement in Sweden. The union's sole original demand went unmet .

How it started: October 27, 2023

The conflict began when mechanics at seven Tesla service centers walked off the job demanding a collective bargaining agreement . CEO Elon Musk and Tesla refused, arguing the company's direct-employee model was superior to union agreements. In Sweden, where roughly 90% of workers are covered by collective agreements without formal legislation requiring them, Tesla's position was a direct challenge to the country's voluntary wage-setting model .

The solidarity campaign: A Nordic multi-union effort

The strike rapidly escalated into the broadest cross-border sympathy action in modern Scandinavia, involving unions from Sweden, Denmark, Norway, and Finland :

Tesla's legal counter-attacks

Tesla fought back in court, but with limited success:

• License plate lawsuits: Tesla sued the Swedish Transport Agency and PostNord over undelivered plates. It won an interim order in November 2023 ordering the Transport Agency to deliver plates within seven days or face a fine . That order was soon overturned on appeal; Swedish courts ultimately ruled that PostNord had no obligation to deliver plates and that the Swedish constitution prohibits government intervention in labor disputes .
• Supreme Court appeal: Tesla's case against PostNord reached Sweden's Supreme Court, which agreed to hear it in May 2026, but the strike ended before a final ruling .

The attrition strategy

Rather than negotiate, Tesla hired non-union replacement workers to keep workshops partially operating and continuously offered individual severance packages to striking workers over time . The number of striking IF Metall members dwindled from roughly 130 to about 80 by August 2026 as workers accepted buyouts one by one .

Just weeks before the end, IF Metall had called new strikes at additional Tesla locations, but with too few members left to sustain the action, the union conceded .

The costs and outcomes

Tesla's scorecard:

• Never signed a collective bargaining agreement in Sweden
• Continued operating through non-union labor
• Avoided setting a Nordic union precedent that could have triggered domino effects across its global network

Costs to Tesla:

• Swedish vehicle registrations fell 67% in 2025, to just 7,252
• Massive reputational damage in a country where collective agreements are the norm
• Legal fees and years of executive attention

Broader implications:

• Test of the Swedish model: The strike was widely seen as a test of Sweden's voluntary collective bargaining system . Tesla broke through it by outlasting the union financially.
• Nordic union spillover: Sympathy strikes across Denmark, Norway, and Finland showed Nordic unions' solidarity, but they could not force Tesla to the table.
• Global signal: Tesla's victory signaled that even in highly unionized markets, a sufficiently determined employer can resist collective agreements if it is willing to pay a steep price in buyouts and lost sales.

The union's own assessment

IF Metall's statement acknowledged defeat: "We can conclude that Tesla is so strongly opposed to collective agreements that they would rather buy out every union member than sign one" . The LO contract secretary Veli-Pekka Säikkälä called the outcome "a failure," though he noted it brought about some changes .

With no members left at Tesla, the union had no labor to withhold. As IF Metall stated: "Today, we end our industrial action against Tesla. We do so because it can no longer have an effect, not because our principles have changed" .
