The automotive and industrial supplier Schaeffler wants to cut another 4,400 jobs in Germany and Europe by the end of 2020 due to the coronavirus crisis.
The headquarters in Herzogenaurach, eleven other locations in Germany and two in other European countries are affected.
A complete closure is no longer excluded for the Wuppertal and Clausthal-Zellerfeld locations.
The company is planning a "socially acceptable implementation" based on the existing agreement with IG Metall.
"Despite an upturn in demand in all three divisions and four regions in recent months, the uncertainty about the further course of the pandemic and the resulting deterioration in the economic situation remains high," said a statement from Schaeffler.
Market and sales expectations for the period up to 2025 only point to a "slow recovery", which is why the structural measures are "absolutely necessary".
Schaeffler hopes that the job cuts will result in savings of 250 to 300 million euros annually.
This is offset by so-called transformation costs of 700 million euros.
Schaeffler has employees at 150 locations worldwide and achieved sales of 14.4 billion euros last year.
Last year, however, the company cut jobs - with the help of a volunteer program that was supposed to cut around 2,000 jobs.
Overall, the number of employees in the entire corporate group has decreased by around 8,250 to 84,223 since 2018.
Schaeffler's competitor Continental also wants to reduce its workforce by around 30,000 jobs worldwide.
According to IG Metall, a total of around 300,000 jobs are at risk in the German metal and electrical industry.
