When will office workers return?

An article in the Economist suggests that:

A year ago, many executives were dubious that productivity could be maintained if employees worked from home. Staff, meanwhile, enjoyed the greater flexibility. Now managers are much more comfortable with the idea. But employees are hankering after the office, at least for part of the time.

Talking to my son in Australia about their very different experience he explained that, when they came out of their comparitively very short lockdown, the traffic and the numbers in work felt as if it had all gone back to normal. Now however it has settled down to more like half the week in work and half - two or three day depending on the job - at home. The traffic has calmed down and the Sidney Business District is quieter than originally.

I think I would like town centres to be more equal in housing and retail/offices but I wonder how that would work in cities.

Apparently, (according to the Economist article again)

Another problem for companies is that employees have become less loyal as the pandemic has progressed. Mr Kropp says that workers are spending more time looking for jobs online and updating their LinkedIn profiles. Since few businesses are hiring at the moment, not many employees have left. But when the economy opens up again, there might be a rush for the exit.

Is this the experience you have heard from the workers in your family? Change will happen; it always does. But what change I wonder?
