The plan was to allow people to choose to move to Dallas and choose a home near HQ or south, where homes are slightly more affordable. Then move HQ ~26 miles north (which falls within the loophole for severance), adding another hour plus of traffic if you live near downtown Dallas. This will NOT be the only move that will be happening. other reporting locations near Dallas are also moving north.
Coincidently the company is aware of what demographics will be most disproportionally impacted. For those employees who live in south Dallas, this will put your drive (in traffic) to about 2.5 hours each way.
