UAW President Bob King is convinced the union will be represented in Volkswagen's plant in Chattanooga by June, he told a German newspaper.
A clear majority of employees at the plant wanted to be represented by the UAW and they have signed a declaration of intent to that effect, King told the Frankfurter Allgemeine Zeitung newspaper in an interview.
VW has called for a formal vote by employees.
"We are also working well with the company. VW has been very fair in its dealings with us and wants its employees to have a voice," King said, adding that the union was not putting pressure on employees at the plant to back the union.
