The clash between IG Metall, government and industry has been a long time coming. Observers say it shows the gradual disintegration of the tripartite social pact which made Germany the world's third-largest economy and its workers among the best paid. 'It is grotesque that, in the worst economic situation in years, IG Metall is making the highest wage claim in years,' said Ottmar Zwiebelhofer of the German Employers Federation. Some 17% of the industries in which the union is represented are already making losses, according to the Gesamtmetall industry employers group.
