German luxury car maker Audi, a unit of Volkswagen, is considering asking its employees to work longer hours without a corresponding rise in pay, chairman Martin Winterkorn said in a newspaper interview. "We have to move away from some bonuses for night work or Saturday shifts," Winterkorn told the daily Süddeutsche Zeitung. "It will be that our employees may have to work more flexibly and for longer hours without a full increase in pay. We're currently talking about this with our workers' council." He addd that the company hopes to cut the manufacturing costs per car in such a way as to keep qualified jobs in Germany. Audi had said at the beginning of November last year that it wanted to cut its costs along the same lines as the austerity program being implemented by its parent company, Volkswagen.
