Once the proposed merger between AT&T Inc. and T-Mobile USA is closed, AT&T is bringing back 5,000 wireless call center jobs to the United States that are currently outsourced to other countries.

AT&T also says the merger will not cause any layoffs for T-Mobile USA and AT&T U.S.-based wireless call center employees who are on the payroll once the merger closes. The 5,000 new wireless call center jobs at AT&T, which is the nation's largest employer of full-time union employees and the only unionized major U.S. wireless carrier, signals the largest push by an American company to bring back jobs to the U.S. since the economic fell in 2008. AT&T has yet to determine where the new U.S. jobs will be located.

"At a time when many Americans are struggling and our economy faces significant challenges, we're pleased that the T-Mobile merger allows us to bring 5,000 jobs back to the United States and significantly increase our investment here," says Randall Stephenson, AT&T chairman and CEO. "This merger and today's commitment are good for our employees, our customers and our country."
