Apple has closed its Elk Grove production plant in California – laying off 235 workers.

Production has been shifted to an outside supplier in southern California, according to reports.

A statement from Apple claims that the measure was a cost-cutting move. The company told Mac Observer: "As part of an ongoing effort to make our operations more efficient, Apple is closing its Sacramento manufacturing operation and moving most of its California-based manufacturing activities to a supplier in Southern California.

"Employees from various other functions of the company will continue to work in Apple's Sacramento facility and while this action will result in a reduction in operations staff, Apple's overall headcount worldwide continues to grow."

The Elk Grove site includes a call centre and distribution centre.

According to the Sacramento Business Journal, workers at the site claim that the layoffs came without warning.

In August Apple bought 800 temporary workers to the plant to help with the roll-out of the Power Mac G5, rather than employ permanent staff. eMacs were also being built at the facility.
