This is of course just informed speculation. But based on the numbers I've heard for L2-L3's in various organizations, the absolutely minimum number for cuts has been about 30% of badged workforce.
This means that of every supervising manager that I know across IT, finance, HR, business, and consumer, the LOWEST number any of them has been given is 30%. Many are at 40% and I've heard number as high as 60%.
Even at the low end of this scale, applied across the company, we are looking at close to 100,000 layoffs. I am not as familiar with the bargained workforce, but I have to assume the numbers won't be as severe.
Just remember, your "leadership" team has fumbled nearly every major step of the past ten years. From bungling T-Mobile, destroying DirecTV, dropping U-verse, failing to build out the fiber network to every home in the footprint, to destroying the company with a disastrous purchase of Time Warner.
All the while, your leaders are borrowing tens of billions of dollars to pay stock dividends on profits that don't exist, because executive compensation is tied to stock price... and nothing else. And they convinced the government to give them tens of billions of dollars of tax breaks and to remove important net neutrality protections. And they remain at the bottom of the list on customer service.
Most recently, you can see this failure in their inability to connect people during the pandemic, by having absolutely no service across huge swaths of their footprint. They abandoned the company's core strength - connectivity - and the company failed the country when it was needed most.
This is scandal-worthy material, but it doesn't mean that it won't have real and profound effects on huge portions of the hard-working employees not in the executive echo chamber.
Good luck and best wishes to everyone during this time.
