According to Press TV, IG Metall aren’t just asking for a pay rise but also demanding the right for workers to temporarily switch to a 28-hour week to care for children or elderly relatives.
Employers say such a drastic change would be illegal and have threatened to go to court to stop the industrial action.
If the two sides can’t agree on the terms of the negotiation by late January, the stage could be set for longer, more damaging walkouts.
So-called “warning strikes” are a familiar feature of the annual collective bargaining process, with workers downing tools for a few hours to demonstrate at factory gates and in town squares.
But there has been no nationwide, open-ended strike in Germany since 2003.
IG Metall expects up to 700,000 to participate in the ritual, running for at least a week from Monday.
Strikes will stretch from Germany’s “rust belt” in western North Rhine-Westphalia State to Brandenburg, Saxony and Berlin in the former communist east and the hyper-modern car factories of southwestern Baden-Wuerttemberg.
At luxury carmaker Porsche, a Volkswagen subsidiary, workers flexed their muscles last week with a Thursday walkout.
Boasting some 2.3 million members, IG Metall is Europe’s largest trade union, representing workers of all kinds in industrial conglomerates like Siemens or Thyssenkrupp, steelmaking, the auto industry, electronics and textiles.
The sheer weight of the metal and electrical industries’ 3.9 million workers often draws other sectors along in its wake when it comes to pay deals — and 2018’s showdown could make for massive changes.
Unions are demanding a pay rise of 6 percent this year.
While the figure is triple the bosses’ initial offer of 2 percent, it is a classic starting position to wring out a compromise.
