T-Mobile is preparing a new round of layoffs at its Bellevue, Washington headquarters, according to a report from the Seattle Times. The cuts come as the company continues to streamline operations as it awaits regulatory approval of its bid to purchased MetroPCS. 

According to the report, employees have already been alerted of the cuts, which will affect over 100 people. 

T-Mobile declined to comment on the matter. 

The Communications Workers of America (CWA) have been keeping a close eye on the proposed merger of T-Mobile USA and MetroPCS. The group has consistently reiterated its position that the merger would mean a loss of jobs. 

In a filing on Monday with the FCC, the CWA claimed that T-Mobile and MetroPCS had admitted there would “job reductions” due to the merger. 

“The synergies touted by T-Mobile and MetroPCS are indeed euphemisms for firing workers, and CWA believes the numbers reflected in those documents are significant, not ‘small,'” the CWA wrote in its filing. 

The CWA also notes that 62 members of Congress submitted a letter to the FCC that proposed joining of T-Mobile USA and MetroPCS should include specific commitments to preserve and grow jobs here in the United States.

If approved, the merger would combine T-Mobile, with 30,000 employees and 33.2 million customers with MetroPCS, which directly employs 3,700 to service about 9.3 million customers.

Just last May, T-Mobile USA laid off 900 workers, which was partially offset by the addition of new employees. The company’s call center workers were the primary targets of a round of layoffs in March of 2012 that closed seven facilities and slashed 1,900 jobs.
