The company is rotten to the core. This has been coming for years. Their executives continually battle over turf, promote self-interest and behaved with monopolistic mindset years after they lost the monopoly. Arrogance and incompetence at the highest levels of the organization have brought them down. It's been coming since 1984.
Actually, there are a few good people who work for the company and many more who have left over the last few years. Other than that, you are pretty close. Some good centers were closed because they did not have the pull at the top.
All of my friends who have left AT&T in the last few years now have better jobs and less stress if they wanted to continue to work. AT&T had great employees and great education programs. Too bad upper management didn't know how to run the company.
