If this change happens it will take many years and will need the government to support it in Internet infrastructure and working from home regulations.
At the moment complaints and concerns are under the radar as we all know its temporary. Millions of people do not live in an abode where they could work from home from for the foreseeable future.
We have a housing crisis and small homes, plus shockingly unreliable Internet across many parts of the country including all over large cities.
I'm all for not propping up retail and turning it into accommodation, reducing how many homes landlords can own, getting rid of the buy to airbnb culture that's come in, advancing work from home technologies, reduction of commute and much more. This is not a simple fix though. Business has seen it works for some of them when they denied it would or wouldn't even consider it; and are now wanking over the the thought of not paying for office space and utilities* with very little concern for employee wellbeing.
The reality is you have living conditions for millions not suited to more than one person using it as an office and often not even one person. Young people especially coming into their first jobs will be vastly at risk of having to work and sleep in the same room.
*so many stories out there of companies expecting employees to pay for utilities being used in business operations due to lack of commuting costs (long before this too).
