The U.S. Department of Justice is taking steps to block AT&T’s proposed merger with T-Mobile. There are concerns the $39 billion deal would drastically reduce competition in America’s cell phone business. Representative Greg Walden says he's received assurances from AT& T officials that no layoffs would occur at T-Mobile Call Centers in Oregon should the merger go through. The Redmond Call Center employs 682 people. About 2200 Oregonians are employed at T-Mobile Call Centers in Redmond, Salem and Portland.
