Unocal Retirements, Separations Pass Goal: The Los Angeles-based oil company said 1,145 employees--45 more than Unocal’s target--have accepted offers of early retirement and voluntary separation. The job cuts are part of Unocal’s plan, announced last April, to increase after-tax cash flow by $200 million a year beginning in 1993. Unocal will take a one-time after-tax charge of $25 million to pay for the retirement and severance packages. The company also said that it is considering the sale of its Imperial Valley geothermal energy assets as part of the restructuring program.
