SCARBOROUGH, Maine — The Hannaford Bros. supermarket chain is offering severance packages as it seeks to reduce the work force at its corporate headquarters in Scarborough, Maine.

Spokesman Mike Norton says the corporate restructuring will have no impact on more than 27,000 workers at the company’s 167 retail stores in Maine, Massachusetts, New Hampshire, New York and Vermont. Nor will there be reductions in trucking and distribution divisions.

He says some corporate positions are already being held open as the company reviews operations at its headquarters, where about 750 people are employed.

The company isn’t saying how many jobs will be eliminated altogether. The voluntary resignation program will offer severance based on tenure.
