Relocate to an area with a T-Mobile "hub" or resign was the "option" I was given surrounding my remote status. Was hired on as remote given a med preexisting condition.
Currently they're offering/giving up to a year for relocation. Not sure if compensation will be included as a lot of these "hubs" are in HCOL areas which is a deal breaker for lots of people including myself.
As they're going forward with this forced RTO, which is currently 3-4 days a week in office, soon it WILL return to the 5 day, hence the pressure on remote workers to move.
When I was hired some years ago, I was told to keep my remote status quiet from my collogues since they were phasing out WFH. TMO is quietly terminating the remote status by doing to roundabout layoff/firings of remote workers who aren't willing to relocate to either a dustbowl or one the most expensive cities in the nation.
