Nearly 90 Washingtonians are being laid off from wireless networker provider U.S. Cellular, including some based in Kennewick and Pasco, as Bellevue-based competitor T-Mobile completes its acquisition of the company initiated last year. 

The state Employment Security Department announced the layoffs late on April 10. Outside of the Tri-Cities, the notice indicated that the layoffs affect U.S. Cellular employees in Yakima, Sunnyside, Union Gap, Longview and Centralia. The employees will be separated on June 2. 

US Cellular is laying off 4,100 staff nationally as it sells its network, customer accounts and some spectrum assets to T-Mobile. In termination letters sent to laid off workers, US Cellular said that it has made arrangements with T-Mobile to offer employment to a majority of the laid off employees at comparable wages and benefits.
