ALCOA, Tenn. - Alcoa Inc.'s Tennessee operations will lose 30 to 60 workers beginning in January through voluntary layoffs, the company said.

The job cuts at Alcoa's 2,000-employee Tennessee operations are part of a local restructuring independent of the world's largest aluminum producer's plans to cut 6,700 jobs worldwide to boost profits.

The "announcement is about Tennessee operations," spokeswoman Melissa Copelan said. "It has nothing to do with the corporate restructuring plan."

The Tennessee plant makes rolled aluminum for beverage cans.

Copelan said she does not expect all the employees to leave the company at the same time.

"There will probably be one exercise in January, with some people leaving at that time, and then another exercise sometime later in the year," Copelan said.

The employees targeted in the Tennessee's operations' rigid packaging division will be offered voluntary separation packages. The company said the packages are "compensation oriented" but would not release details.

Copelan said Alcoa will continue to invest in Tennessee employee training and development and will still need to hire for specialized positions.

"Our overall numbers may be lower, but I can assure you we will continue to invest in our employees and develop and train them to the fullest extent," she said.

The company's global cuts announced earlier would represent about 5 percent of Pittsburgh-based Alcoa's 129,000-employee work force. Company officials said at the time that would result in 20 job losses from the aluminum company's canned sheet facilities in Tennessee, Indiana and Russia.
