"STUTTGART, Germany (AFP) - Friction is mounting between German automaker Porsche and workers at Volkswagen, where employee representatives fear losing their influence if VW is swallowed up by Porsche.

Porsche head Wendelin Wiedeking fired the first shot earlier this month, unveiling his plans to take control of Volkswagen, the German group of which Porsche already owns about 31 percent.

Adding to the tension, he let it be known that if his plans bore fruit, there would be no more "sacred cows" at VW, where employees enjoy advantageous working conditions thanks to collective bargaining agreements.

Porsche finance director Holger Harter this past weekend disclosed in an interview that his company did not intend to include a VW representative on its board of directors if the takeover went ahead."
