DAYTON, Ohio (Jan. 8)—Delphi Automotive Systems said 289 jobs at its Delphi Harrison Thermal Systems plant in Moraine, Ohio, would be eliminated effective Jan. 8 to adjust staffing to reduced vehicle production volumes. The world´s largest automotive supplier also said it will temporarily lay off more than 1,100 employees in the state, beginning this week. Included in that count are 305 workers at Delphi´s engine mount, brake hose and brake assembly operations in Dayton and Vandalia. Delphi will re-evaluate the layoffs on a weekly basis, a spokesman for Delphi Chassis said. The layoffs come in response to announcements by General Motors Corp. that it would cut production at eight of its plants this month, preceded only a day earlier by DaimlerChrysler A.G.´s announcement it would idle several of its plants during the same period.
