Working at AT&T is high risk since performance reviews are political and not based on performance. Buying a house, a car, having children and not knowing if the job or career is going to be there because of upper management bad investments over the past 10-15 years is a cr---y way to live. Not to mention the health insurance eroded year after year where the cost is very high.
Your stress will reduce, health will improve, family will appreciate the lower stress.
Do not wait to get laid off, do it on your terms, start job search now, use time wisely now prior to layoff to get current and up skill to what is going on in industry, because AT&T internally is not doing best practices despite selling those words to customers.
The company is really still SBC in AT&T logo/clothes. The values, culture, diligence, technical excellence of legacy AT&T have been long gone. The move to Dallas proved it.
