May 22 (Reuters) - The U.S. agency in charge of enforcing labor law has asked workers at Volkswagen AG's Chattanooga plant to refile their petition for a union election, after having dismissed an earlier one, the United Auto Workers (UAW) union said on Wednesday.
The National Labor Relations Board (NLRB) decision comes a day after three Democratic U.S. senators urged the German automaker's U.S. unit to drop efforts to delay the election at its Tennessee assembly plant.
Volkswagen had won a bid to put off a union vote for 1,700 workers at the plant earlier this month.
"Volkswagen has continued to use legal games to aggressively deny its workers the right to vote for years," the UAW said in a statement.
"It's ridiculous and shows how broken the rights of workers are under our labor laws. But we will be on the NLRB's doorstep immediately to file again and demand a speedy election." (Reporting by Ankit Ajmera in Bengaluru; Editing by Shailesh Kuber)
