Up to 11,600 workers could be made redundant as part of the widespread restructuring at Siemens that aims to save the company €1bn a year.
Joe Kaeser, the CEO of the German engineering giant, revealed the information during an investor conference in New York on Thursday.
Kaeser, appointed Siemens’ CEO nine months ago, introduced the long-awaited restructuring plan earlier this month. The plan will see Siemens’ organisation being cut back to nine core divisions. Previously Siemens had been structured along sectoral and regional lines.
"We do away with the four sectors. 7,600 people work in sector coordination, coordinating a middle layer that is gone. Another 4,000 people were doing a regional cluster analysis, which is not necessary anymore," Kaeser said at the conference.
Responding to queries about the numbers on Friday, a Siemens spokesman said that not all of the employees mentioned by Kaeser would end up losing their jobs. He noted the company's previous savings plan, launched in 2012, had involved 15,000 positions but had resulted in an overall headcount reduction of 4,000.
Siemens employes 360,000 staff worldwide, with about a third in Germany.
"For now, Mr Kaeser has only said how many positions are affected by the organisational restructuring," the company's spokesman said by email. "But removing jobs in one area does not necessarily have to mean job cuts."
Kaeser's predecessor Peter Loescher ran into trouble with unions when he tried to push through job cuts. He was pushed out last summer after a series of profit warnings.
Kaeser has vowed to restore a sense of pride at Siemens, which traces its roots back to an electrical telegraph company founded in Berlin in 1847.
He will be keen to avoid a showdown over job cuts that might distract from his ambitious corporate overhaul, dubbed "Vision 2020", and from separate plans to bid for the power assets of French rival Alstom, which is already the target of an offer from US giant General Electric.
"The number that is circulating has not been discussed with us," a spokeswoman for the IG Metall union - which represents engineering workers - said on Friday. "We are waiting for the talks."
