North Andover, Mass.--Lucent Technologies Inc. said late Tuesday that it expects to lay off 1,000 workers statewide, double the amount of cuts previously announced. The company on Monday gave a 60-day notice to 725 union-represented workers at its Merrimack, Mass. facility, and 75 managers will be notified by the end of the month, said William Price, a spokesman for the Murray Hill, N.J.-based company. The other 200 layoffs will occur at other facilities in the state. Some of those notified could get their jobs back if others accept voluntary retirement, Price said. Since January, Lucent, a major b-to-b player, has announced plans to reduce its work force by up to 16,000 jobs as it streamlines operations and sells off some of its factories. At the time it said it expected about 500 Massachusetts job cuts. Shares of Lucent fell 98 cents to $7.85 in trading on the New York Stock Exchange.
