What the policy says.

In 2021 T-Mobile used 'work styles': resident (office-based), hybrid and flexible.
CEO Mike Sievert's internal email of 2021-08-31: 'Our spaces are open and ready for you, and it is time to come back regularly.'
The 2021 return to Seattle-area and Kansas City offices required vaccination; unvaccinated staff could ask to stay remote.
Anonymous employee posts (January 2022 to April 2023) describe a three-day minimum, with some teams requiring more or less.
A March 2023 anonymous post says badge-scan data was used to build attendance lists (unverified).

Sources and how sure we are.

UnconfirmedReporting is thin, old or conflicting. Treat it as a lead, not a fact.The current policy hasn't been confirmed for 2026. No T-Mobile memo, press release or major news report from 2022-2026 stating a company-wide day count has been found; the three-day figure rests on anonymous Blind posts and may not hold if the policy is truly team-dependent. The January 2022 start date is approximate, taken from the earliest employee report.
