Wolfsburg – Volkswagen is heading for a labor dispute in Germany before Christmas in a dispute with its workforce over billions in savings. IG Metall is now preparing for warning strikes from December, said IG Metall negotiator Thorsten Gröger. He will recommend to the collective bargaining commission “that we also call for warning strikes at Volkswagen locations once the peace obligation expires, i.e. from December 1st,” said Gröger after the third round of negotiations.
