Sprint is reportedly in the process of laying off hundreds of employees at its Kansas City-area headquarters.

The job cuts are the latest in the years-long effort by the nation’s No. 4 wireless carrier to curb costs in order to help fund investments in its network.

Company spokesman Dave Tovar told The Kansas City Star that the 500 cuts could include any of the 6,000 employees at the campus in Overland Park, Kan. Some individuals were notified as of late last week, but supervisors were still in the process of identifying other cuts, he told the paper.

“We realized there were some redundant jobs, and looked at how we could combine areas of the company under a smaller leadership team,” Tovar told the Kansas City Business Journal.

Company officials noted that Sprint plans to open 600 retail locations this year, along with another 850 locations for its Boost Mobile prepaid brand, which are expected to create thousands of jobs.

Sprint’s workforce will also climb as it makes network investments that were delayed as the company discussed a potential merger with T-Mobile.
