 A United States attorney has stated that no evidence was found to back up Coughlin's initial claims, and Walmart continues to deny the existence of the anti-union program, though Coughlin himself apparently restated those claims to reporters after his conviction.Walmart has also had some run-ins with the German Ver.di labor union as well.These issues, combined with cultural differences and low performing stores, led Walmart to pull out of the German market entirely in 2006.
