That's right.
My old firm was in Leeds with a big office which largely became call centre. Then they spread out to several other big call centres, all in cities spread over N England. There's no reason why, given suitable premises in which they could have taken small spaces, they couldn't have set up multiple small centres and recruited locally to them.
This big centre, long commute model of working isn't sustainable. The longer it takes that to sink in the worse will be the problems of sorting it out. An intelligent government would be looking at tax incentives to drive working at home or locally but those are rare and the current one seems to be on the less intelligent end of the spectrum.
The planning policy which has dictated the present situation was a response to C19th slum dwellings clustered round heavy, polluting industry. By and large that's not the problem now but the policy hasn't changed.
