This seems to be the real reason that AT&T is pushing RTO, including telling people that have worked remote for their entire careers and never seen an office in 20+ years that they must relocate to a designated location either by the end of 2023 or 2024 depending on their wave. If they reject immediately they will get severance, but if they accept and don't relocate later they will be terminated without severance.

Although the story says that "managers" (e.g. non union individual contributors) get to choose from the 9 locations, that's not the reality, your work stream is assigned a designated location, there may be an alternate location you can petition to go to instead but it must be approved first.
