I stumbled across an HR site when looking for surplus information that stated the nine core hubs at AT&T has planned.
Dallas/Plano
Atlanta
El Segundo, California
San Ramon, California
Bothell, Washington
Middleton, New Jersey
Bedminster, New Jersey
Washington DC
St. Louis, Missouri
I was doing a search on the on the one stop site and it was a frequently asked questions about where and how we work.
It also stated the core locations are long-term strategy of where we work.
Also stated that they will be closing locations as a consolidate over the next two years.
Take that info and face value because you know that could change!
