Signet Jewelers, parent company of the largest U.S. mall-based chains Kay and Zales, has cut additional employees at its Texas and Ohio corporate offices.

But the company wouldn't say Thursday how many people are being let go.

The job eliminations have come after voluntary and forced layoffs announced in February and March weren't enough to meet unstated goals for cost savings. So far, the company eliminated 180 jobs, or 20 percent of its Irving workforce, with the decision to consolidate the jewelry manufacturing and repair operations to Akron, Ohio.

The voluntary severance was offered to 3,400 corporate staffers, who had until the end of March to decide. Signet also plans to close 150 stores this year.

Signet had employed almost 800 people in its Irving office and 2,608 at its Akron corporate office. Zale Corp., which was Irving-based, was acquired in 2014 by Signet.

Spokesman David Bouffard reiterated that the company has no intention of leaving North Texas.

"We have repeatedly stated our commitment to our Dallas operations," he said in an emailed statement Thursday. "In order to make our company more agile and efficient and to fund needed investments in infrastructure and growth initiatives, Signet's making significant transformation efforts. We are consolidating as is necessary to reduce our workforce through voluntary and involuntary separations."

All employees being let go are being offered outplacement services and separation benefits, the company said.

Signet moved its Texas operations into a new 250,000 square foot building in the Irving section of the Cypress Waters development along LBJ Freeway in 2016. The company has already returned to the landlord about 37,000 square feet of space that it no longer needs following the closing of a manufacturing and repair operation.
