I'm not hearing about any problems with wireless, although there is a concerted effort to automate the network. But that is AT&T in general. There will be the usual effort to streamline and so forth.
But the layoffs we're going to see on this board involve the technologies that are going the way of the dinosaur, namely landline telephone. Wireless, WarnerMedia, and even Business Wireline is doing well, or good enough.
It is the Entertainment component, that includes Direct TV, Now, residential telephone, internet, etc that has declining income contributing towards AT&T Inc., which is a self-described holding company of several subsidiaries.
So, automation will create redundancies, but the big problem is in the component that has income that will approach or go below $0.00 if nothing is done.
It is not one company. It is a holding corporation, with many subsidiaries.
Tend to agree with the things stated in this post by @XjA3vwz-rir
