The maddening thing is that it could be a game changer for the environment, for many working people's quality of life, for the quality of family life and good in so many ways.
Employers still need to be able to achieve on the job training by having new staff working alongside experienced staff in everyday workplace scenarios. Some employees would suffer emotionally from the withdrawal of contact with their work colleagues.
IMHO what is needed is a balanced approach to reap environmental/social benefits from less commuting but without forcing a total change on those employees left feeling isolated by reduced face to face contact. Could salaries reduce to share the travel cost saving with the employer or wfh be offered instead of a pay rise ? Could the reduction in the need for office space lead to alternative uses being found and some buildings being re-purposed ? Could businesses currently dependent on prime site office space, reduce their costs sufficiently to be able to pass on a reduction in the cost of their goods/services to others ? (not a commercial suggestion, I know
)
Sadly though, I suspect that far too many people will be forced back into full time commuting because some (dinosaur) giants of the commercial world are currently vehemently opposed to the idea and shouting their opinions loudly enough to drown out reasonable opposition and coerce a business-centric government into supporting those views.
The thought that, OMG, people might spend less on travel and lunches, work clothes etc seems a very short termism argument for reverting back to the way things were. Yes, some business models may go to the wall but people will spend on other things and in other ways that fit in with an new working pattern thereby still generating revenue for the government in the form of direct and indirect taxes. Other businesses will expand, new opportunities be identified.
We shouldn't be pandering to wealthy institutions/individuals who have looked at their exposure to the business land and premises market or their coffee shop or sandwich shop or fashion chain empire and panicked.
