With the US Department of Justice recently giving its go-ahead to T-Mobile's merger with MetroPCS, reports - citing sources from within T-Mobile - have now revealed that T-Mobile will likely slash a number of jobs at its headquarters.

Since there were concerns already looming large that the T-Mobile/MetroPCS merger will lead to massive job losses, `inside' sources have disclosed that the impending job-cuts at T-Mobile will apparently affect more than 100 employees from marketing and other divisions of the carrier; and the move will probably take effect from Thursday.

According to the sources, the job-cuts will chiefly affect the employees working at the T-Mobile headquarters in Bellevue. Thus far, these employees have remained more or less shielded from the layoffs which had been issued by the carrier over the last few months. Out of the over 4,200 jobs which the carrier had slashed in 2012, a majority - nearly 3300 jobs - of them affected the employees working at its call centers.

Employees are seemingly already aware of the impending job-cuts which T-Mobile is reportedly set to put in place this week onwards; especially after T-Mobile and MetroPCS had revealed in their October-announced plans that they would "combine forces" for creating the "leading value carrier in the U. S. wireless marketplace."

Going by a report in The Seattle Times, T-Mobile's employees at the carrier's headquarters are girding themselves for "a significant round of layoffs," prior to the carrier's merger with MetroPCS which appears to be on the fast track.
