General Motors Corp. is offering early-retirement incentives to U.S. salaried workers as it cuts an unspecified number of jobs to reduce costs and improve efficiency. The world's largest auto maker set no target for how many workers it hopes will accept the offer. The Detroit News reported that 1,000 jobs would be cut. GM declined to confirm or deny that report. Under the offer, eligible salaried workers age 58 or older with at least 30 years at GM can retire with full pension benefits, while those ages 50 to 58 with 30 years of service can retire with reduced pensions, a GM spokesman said. The offer won't be made to everyone who meets those requirements, he said. Separately, GM Vice Chairman Harry Pearce said his return to a full schedule at the auto maker after undergoing treatment for leukemia does not signal that Chairman John F. Smith Jr. is about to retire, contrary to recent speculation.
