FRANKFURT, Dec 20 (Reuters) - DaimlerChrysler's designated Chief Executive Dieter Zetsche intends to eliminate around 8,000 more German jobs without adding more money to the 950 million euros ($1.14 billion) set aside to finance 8,500 cuts at Mercedes, a source familiar with the situation told Reuters on Tuesday. "Zetsche wants to do this via attrition," the source said, adding Zetsche had told the supervisory board he was not prepared to add to the already-approved 950 million pot.
