The Workforce AI Index · Communication Services
T-Mobile US, Inc. (TMUS)
Wireless carrier, one pattern, all U.S.. Read October 1, 2026 from the annual report for the period ending 2025-12-31, filed 2026-02-11. Ranked 3 of the 10 Communication Services companies read so far, by the share within reach now: the sector.
The filing states approximately 75,000 full-time and part-time employees, substantially all in the United States, in one wireless business, so one telecommunications pattern carries the workforce (c).
The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.
What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 26% now, 42% at the end of 2027, 49% at the end of 2028, 51% at the end of 2030. By the patterns, the work is about 51% desk work, 20% people work and 29% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 49% of the working time stays with people (conversation, in-person and hands-on work), 38% becomes checking a model's work and 10% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
Headcount
75,000 employees as of 2025-12-31 (stated). The filing states that substantially all employees are located throughout the United States, including Puerto Rico, without a count.
The filing: “As of December 31, 2025, we employed approximately 75,000 full-time and part-time employees, including network, retail, administrative and customer support functions.”
