Stuttgart, Germany - Germany's powerful metalworkers union said Friday it would launch at the weekend its biggest campaign of strikes ever for higher pay in manufacturing industry.
At 24-hour-per-day factories, hundreds of workers will skip a shift Saturday.
The union, IG Metall, said it would then ramp up the strikes late Sunday by calling out tens of thousands of workers.
That would idle manufacturing plants of Volkswagen's premium-car division Audi, with 4,000 workers expected to stop working at just one Audi plant, in Ingolstadt.
