CLEVELAND (Nov. 15)—Eaton Corp. plans to cut 10 percent, or 90 positions, from its corporate staff in Cleveland and will notify affected employees today. In a letter sent Nov. 13 to all corporate-level personnel, Eaton Chairman and CEO Alexander M. Cutler referred to the cuts as "regrettable and difficult." They are necessary, he said, to size expense levels with the reduced activity levels in Eaton's end markets. "While we cannot control the economy, we must—and will—actively lead Eaton through this period of economic weakness," Cutler said in the letter. Eaton cut 600 positions from its Fluid Power business this summer to compensate for declines in hydraulic orders and to further integrate the former Aeroquip-Vickers Inc. operations.
