Stay the entire 60 days and look for a job internally. Chances are you will not find one internally, but try anyway. Milk all the resources you can from the company while you are still there. Do not use your PTO, instead take any FMLA, Paid Sick time, etc. You will get paid in lieu for PTO but not sick time, so use it if you need it. Make sure you take care of all Medical, Dental and Vision appointments BEFORE your last day on payroll. Pay off as many debts as you can while you still receive paychecks. Utilize their external out-placement program, it is very helpful and free! Don't use the lame surplus training the company provides. DO NOT QUIT, wait to get surplussed and get the Severance Pay and/or Unemployment Benefits that you are entitled to! You will need them while looking for another job externally. Make sure you get sound advice from Fidelity on what to do with your 401k and Pension once you leave. Once you are gone, take a little break and remember that NO COMPANY is run as poorly as AT&T and you will need time to prepare yourself mentally for your new job.
Most importantly, know that there ARE other jobs out there and AT&T is not the only place to work! YOU WILL FIND ANOTHER JOB and YOU MAY ACTUALLY LIKE IT AND GET PAID MORE!!
God Bless You ALL and enjoy the next chapter of your life/career/retirement!!!
In case you were wondering, I was a manager in ATO California surplussed 3/29
