I think a lot of it will depend on how long the virus restrictions last, the longer we spend doing it the more people will get used to it and potentially enjoy it - I know not everyone does though so I can see in the future perhaps offices will shrink and become ‘hubs’ for some people to work from and others to maybe pop in for meetings and such things.
A lot will also depend on the business, only clerical or computer type jobs really work, I don’t imagine many welders or carpenters will be working from home unless they just manufacturer and sell small pieces.
A lot will also depend on broadband speeds - I am fortunate to have a very good connection but I know many people that have very poor connectivity where they are.
