AT&T

None, unless you are planning to retire soon and have no motivation to succeed in your career.

Lack of competency, poor work ethics, very low hiring standards, bureaucracy, and politics.

It is not important what you know but whom you know in the company to get promoted or get a raise. Most of the work gets done by hiring local contractors who barely have knowledge or the qualifications to do the job.

If you can get a job nowhere else, then you are bound to find one here, which is not a bad thing to bring food to the table.

Hire qualified people, improve working standards, and treat employees fairly. The middle management needs lots of training, as they do not have the leadership skills to manage or lead a group. You not only need to raise the bar of the wireless signal, but also the bar of the people who work in the company.
