This seems somewhat different than the return to office discussions that have been had recently.
If these people were hired to work remotely, then they never were in the office, when offices went to remote work.
It seems different than the situations, where people were working in an office ,were sent home, and now are being asked to come back to the same office. In this case most of these people probably do not live in or near the Hub cities they are supposed to go to work in.,
As is true of any job ,if the pay and benefits are worth relocating for, then some people will relocate to those Hub cities.
We have a pretty much 100% in the office policy now.
