Skilled trades workers at the Volkswagen plant in Chattanooga, Tennessee, voted in 2015 to come together in a union to create a better workplace.

Sign the petition to tell Volkswagen CEO Matthias Müller to end the company’s anti-union campaign and we’ll include your signature in a petition at the Volkswagen shareholder meeting.
