Mercedes-Benz settles case over alleged US union-busting

Mercedes-Benz has reached a settlement with the US National Labor Relations Board (NLRB) over alleged union-busting efforts during the UAW’s 2024 organising drive at its plant in Alabama. Under the agreement, Mercedes must distribute a notice to employees stating it will not threaten plant closure or relocation to a non-union location, will not threaten loss of benefits, and will not unlawfully surveil or interrogate workers over suspected union activity.

The settlement brings to a close the fallout from a May 2024 vote in which workers rejected United Auto Workers representation 2,642 to 2,045. The union immediately contested this result, alleging that Mercedes-Benz had illegally interfered to prevent a fair ballot from taking place. Alleged violations included mandatory anti-union meetings at the plant, retaliation against individual union supporters, and the dismissal of a pro-union worker on false pretenses. A separate NLRB petition to overturn the election result remains pending.

The Vance plant employs approximately 6,000 workers and serves as Mercedes-Benz’ global lead production site for large luxury SUVs, with around two-thirds of its output exported to more than 135 markets through the Port of Mobile.

In a statement, Mercedes-Benz emphasised that it did not admit to any wrongdoing as part of the settlement. Rather, it agreed only not to take such actions in the future. “We look forward to working directly with our team members on measures to ensure we remain an employer of choice and provide a safe and supportive work environment.

The UAW objected to the settlement terms, arguing that Mercedes-Benz management should be required to read the rights notice aloud to workers rather than simply post it online where it would otherwise be buried. NLRB regional staff rejected that condition, with General Counsel Crystal Carey stating that a mandatory oral reading is reserved exclusively for more egregious cases of labour violations. Despite the union’s objection, the agency approved the settlement in its existing form.

The case looks like it will carry implications far beyond Alabama. The UAW has filed a separate complaint under Germany’s Supply Chain Due Diligence Act, which requires that German companies ensure labour rights are respected across their global operations. Germany’s BAFA agency has opened a formal investigation; a finding against Mercedes could result in fines of up to 2% of its global revenue. 

The German legal front is arguably the more consequential pressure point. US labour board settlements are generally forward-looking and non-punitive in nature, but a BAFA finding would carry financial penalties and reputational damage at the corporate headquarters level. It is highly likely, then, that Mercedes-Benz’ leadership in Stuttgart will be watching the German investigation far more closely than the Alabama notice-posting requirement.

Mercedes-Benz’ plant in Alabama remains the only one in its global production network without union representation.
