Pros
There's really not much to say here. I believe this was once a good company to work for, but those days are long gone.
Cons
Benefits are horrible. The company could care less about employee morale at all levels (lowest morale I've seen anywhere). There's zero career path mentoring/opportunity. Everything is automated. No tools, resources, or support to actually do your job (you can't even get office supplies in corporate offices). Upper management....wow....that's about all I can say. AT&T has mastered the art of not living up to internal and external commitments, without taking accountablitly. There' a complete loss of trust and respect for the company and senior management. And to top it off, they play the fear card in a bad economy, and tell employees to find another job if they don't like it. What a great place to work....
