T-Mobile may not fulfill a key promise made during its merger with Sprint.

T-Mobile stated in 2018 that post-merger, their headcount would exceed the combined total of T-Mobile and Sprint. However, upon the deal's announcement, the company mentioned identifying $43 billion in synergies, a figure potentially reliant on eliminating redundant positions. While the CWA's warning of 28,000 layoffs did not materialize, T-Mobile's pledge of a "jobs-positive" outcome has not yet been realized.

With T-Mobile pushing representatives and customers to use the T-Life app for account management, phone upgrades, and bill payments, the company seems to be shifting towards a digital Mobile Network Operator model, which involves store closures and representative layoffs to boost profits and stock value.

SEC filings and Deutsche Telekom's quarterly reports show that in 2019, as the FCC and DOJ reviewed the merger, T-Mobile had 53,000 employees, while Sprint had 27,000. The combined 80,000 was reduced to 75,000 a year later. By 2023, the company employed 67,000, a decrease of 13,000 or 16% since the acquisition.

Despite the decline in full-time positions, T-Mobile has increased its part-time employee count since the merger. Last year, the company added 3,000 employees, and Deutsche Telekom reported nearly 2,500 new U.S. employees. Their annual report stated the increase in full-time equivalent employees in the U.S. operating segment was 4.0% higher than the end of 2023, mainly due to more retail employees supporting the growing customer base.

Deutsche Telekom's U.S. employment continues to grow. By September, the telecom giant had 70,989 full-time U.S. employees, 5,835 or 9% more than at the close of 2024. This gain stems from the acquisitions of Vistar Media and Blis in advertising tech, and UScellular in wireless.

Even with these acquisitions, Deutsche Telekom's full-time U.S. employment at the end of September was 5,100 fewer than in 2020, immediately after the Sprint purchase. Declining employment is not unusual in the wireless industry. Verizon recently announced 13,000 layoffs following the appointment of a new CEO, adding to the 32,000 jobs cut since 2020.

AT&T has reduced its headcount by 95,000 employees during the same period. With concerns about AI displacing jobs, the industry's job outlook is uncertain. T-Mobile's shift away from retail stores and human representatives further darkens the picture.

Despite T-Mobile's unfulfilled promise of job growth following the Sprint acquisition, the situation could have been worse without the merger. Sprint was struggling, and more Sprint employees could have lost their jobs. T-Mobile acquired Sprint mainly for its 2.5GHz mid-band spectrum, a key element for its 5G leadership goals in the U.S.
