According to the Verdi union, Deutsche Post postmen and parcel deliverers should receive 15 percent more money.
This requirement for 160,000 domestic employees will be the subject of collective bargaining, which will start on Friday.
The company rejects the 15 percent requirement as "unrealistic".
"In the upcoming collective bargaining negotiations, it will be important that we find the balance between wage increases for our employees and economic viability for the company," said a Post spokesman before the negotiations began.
He emphasized that the company must remain financially viable for investments.
Verdi negotiator Andrea Kocsis, on the other hand, considers the strong wage increase to be “necessary, fair and feasible”.
"The employees urgently need inflation compensation and they also expect a share in the company's success," said the trade unionist, referring to the recently brilliant figures of the globally active group.
"Heavy Duty"
The employees had worked "under the highest stress" in recent years, and now they expect "permanent financial recognition of their work, which is so important for all of us".
At the start of the negotiations, both sides are only expected to be scanned for the first time.
Almost two weeks later, the next round of negotiations should continue.
The negotiations at Deutsche Post are the prelude to further collective bargaining in 2023. Talks in the public sector will begin on January 24th.
For the more than 2.5 million employees who are covered by the binding effect of the TVöD, the employee side is demanding 10.5 percent more wages.
