NASHVILLE (AP) - Volkswagen would become a "laughingstock" if it goes through with a deal to have the United Auto Workers represent workers at its Tennessee plant, U.S. Sen. Bob Corker said Tuesday.

The Tennessee Republican told The Associated Press in a phone interview that he was dismayed when VW last week sent a letter to employees regarding its discussion with the UAW about creating a German-style works council at the Chattanooga plant.

"For management to invite the UAW in is almost beyond belief," Corker said. "They will become the object of many business school studies - and I'm a little worried could become a laughingstock in many ways - if they inflict this wound."

Corker, who played a large role in persuading Volkswagen to build its lone U.S. assembly plant in the city where he was once mayor, said he hopes the company pulls back from its decision to engage in talks with the UAW.

"We've talked to management, and to me i t's beyond belief that they've allowed this to go that far and displayed this kind of naivety that the UAW is somehow different than they were years ago," Corker said.

The Wolfsburg, Germany-based company has faced pressure from labor representatives on its supervisory board, who have called it unfair for the company to deal with organized labor at every one of its major facilities around the world except for at its U.S. plant.

"The Volkswagen Group respects the employees' right for an employee representation on plant level at all locations worldwide," the letter from the plant managers said. "This certainly also applies to the Chattanooga plant."

According to the letter, the discussion with the UAW is necessary because a works council can only be established in the United States through an established trade union. Some experts have disputed whether that's a requirement, and politicians such as Corker have suggested the UAW should be left out of a works coun cil at the plant.

"There's plenty of unions other than the UAW," he said. "Why would they choose one that has created such a mentality in these plants of us-versus-them?"

Corker said the Southeast would become less attractive to foreign automakers if the UAW gains a foothold, adding that he worries that Volkswagen would become less competitive if the UAW represents workers at the plant

"It's still incomprehensible to me that they would be where they are," he said. "I'm discouraged and I do hope they will pull back from this."

A UAW spokeswoman had no immediate comment on Corker's statements. A Volkswagen spokesman declined to comment.

Corker and the UAW have been at odds since he pushed for wage and benefit concessions for union workers as part of the government bailout of automakers in 2009. Corker maintains that his role in the discussions helped the auto industry emerge from the economic crisis in stronger shape.

Many union workers at th e General Motors plant in Spring Hill, Tenn., blamed Corker for the facility being idled during the company's bankruptcy, and argue that contract negotiations ensured that auto assembly was restarted with jobs that would have otherwise gone to Mexico.

Corker said Tuesday that while he's pleased the GM plant is back to producing vehicles, he's concerned about the work environment in Spring Hill.

"I have never witnessed anything like I have seen down at Spring Hill. And to see management genuflect to the UAW," he said. "It's not a healthy situation."

Entry-level workers at Volkswagen's plant in Chattanooga earn $15 an hour, which is similar to the starting income of UAW workers at GM, though the current contract imposes a cap of 25 percent of workers making that wage by 2015.
