German plants affected employ more than 15,000 people.
The dapd news agency has reported hat Opel said it is in talks to shorten hours at its main plant in Ruesselsheim and at a smaller plant in Kaiserslautern. An agreement is expected soon.
The company wouldn’t say how many workers could be affected, but Ruesselsheim employs some 13,000 people and Kaiserslautern 2,500.
GM has been shaking up Opel in recent weeks, replacing many top managers including its CEO, CFO and head of research and development.
GM has made clear it is determined to return to profitability its money-losing European business, which includes Britain’s Vauxhall, despite tough competition among mass-market carmakers.
