Some may be planning to earn packet switched technology certifications or an online degree as a strategy to move into a more secure position at CenturyLink. It's a given that those who are planning to do this are the higher motivated top performers in their departments.
For those making such plans, you should be aware that one of the impediments to your plans may be your supervisor or managers if you are a top performer who makes them and your department look good. This is a problem that has always existed industry-wide in local telecom companies for as long as there has been local telecom companies. Not all supervisors and lower level managers will attempt to hold you in your current position to continue making themselves look good, but many will.
It's not a problem that most upper level managers are aware of, or care about. Upper management lives in an upper management bubble, and they could care less if your supervisor would do everything possible to keep their top performers in their department.
Therefore you are mostly on your own when planning how to solve this problem. Certainly the most effective resolution to this problem may be to simply leave CenturyLInk altogether, but before you do that, I would recommend that you contact management levels who may be able to help you achieve your professional goal. If you suspect that your manager is the type who will hold you back for their own self interest, making your plans known to higher levels of management, and the managers in the departments you are interested in working within could help. Also, letting your supervisor know that you will not tolerate such reprehensible conduct may help.
CenturyLink needs motivated, skilled technicians and engineers just as much as any other telecom company to stay competitive, and it is in everyone's best interest that the most motivated and skilled technicians and engineers advance into the jobs where they are needed. Therefore, if you are planning to commit your money and time into advancing within CenturyLink, now would be a good time to think about how you will solve this problem should it arise.
I would recommend talking to a career planner in HR if they have not all been terminated, and see what assistance they can provide in achieving your goals within CenturyLink.
