Hi. Just to clear up the whole COBC comment, that is flat wrong. You may say "yes' to move and opt against it at any time. You can not be terminated for changing your mind but you will find yourself in the surplus list. Whether or not you are eligible for severance is another story.
In any case, I would never recommend moving for a position with this company. Yes, a job is important but remember, this is at&t we're talking about. They do not care about us. Whether you sit in Plano or Frisco or downtown, you are still surplus-ready. AT&T is overstocked when it comes to employees. Even the bootlickers and shills get axed. It doesn't matter. In fact, in the new AT&T, you can bet that simply being a cheerleader or a head-nodder will not be enough. You need to be a thinker and a producer. We are not in a good place. Fiber and mobile are not enough to sustain a company of this size. We need ideas. Being stup1d but agreeable is not enough. Having an accent is not enough.
If you are prepared for the tough road ahead and feel that you and your significant other (where applicable) are employable in the market you're moving to, great. Take the move if that is where you want to live. if not, you have a hard decision.
Do you move for a company whose market focus is on mobility and remote solutions while being unwilling to walk the walk? Look, the longer you stay, the more you look unwilling or unable to leave. That never looks good on a resume. Think for yourself, if you can.
