That's exactly what AT&T was doing right before the pandemic, different groups were being assigned to specific offices and if you weren't willing to relocate to where your group was being moved to you would (if you were lucky) get laid off but many were simply let go for refusing to relocate without any kind of package. They ended up outsourcing about 1/4 of their IT dept to IBM in 2019 after they had done about 7 rounds of layoffs due to geographic consolidation.
If the goal was to get rid of mostly older (40+) year old employees who had families and didn't want to move, sure. Since the pandemic they have allowed most people to work remote, some are on a hybrid 1-3 days in the office schedule and they are supposedly planning on trying to tell everyone to start coming to the office full time in April. They lost a lot of elderly employees at the end of 2022 due to retirement plan changes that encouraged many to retire early and they're probably about to do another big layoff in March. They still haven't returned to a geo-centralized skill strategy. AT&T has been unloading real-estate since before the pandemic, they are consolidating into 6 data centers down the dozens they currently have. If they get a bunch of stealth layoffs out of the deal, they're quite happy with that.
