Last March, T-Mobile announced it had cut its workforce by 5% in the wake of the blocked merger with AT&T. Now, Brier Dudley of the Seattle Times reports, the company is gearing up for a new round of cutbacks:

T-Mobile USA Chief Executive Philipp Humm warned employees a few months ago that more layoffs would happen by the end of May. It’s happening right on schedule.

Today, the company is informing employees of “a series of organizational changes,” a spokeswoman said.

A net loss of about 900 jobs will result. But even more jobs are likely affected by the changes, which include layoffs and shifts to outsource more work.
