Supermarket chain Albertsons on Wednesday said that it will reduce its store workforce by about 2,200 to 2,500 positions across all 247 Albertsons stores in California and Nevada.

The Fullerton subsidiary of Eden Prairie, Minn.-based Supervalu Inc. did not say how many workers in Los Angeles County would be affected by the layoffs, but the chain has about 60 locations here according to its web site.

Albertsons said the reductions would begin the week of June 17 and should be completed by July 1. It said it would work with affected employee unions to make the reductions in conformance with collective bargaining agreements.

Supervalu acquired Albertsons – the largest of its 12 regional grocery chains – in a 2006 deal that greatly expanded its presence in the West Coast and Rocky Mountain regions. The recession and debt load from acquisitions are considered among several reasons the company struggled to capitalize on the expansion potential.

“While Albertsons’ commitment to the neighborhoods it serves remains the same, the need for change at the company is clear,” the company said in a statement. “Albertsons has not kept pace with the changing needs of its customers for a number of reasons.”
