I was chatting with someone earlier and I said that most people currently working from home will be working from home now permanently. There will be no switch back to the offices in the city.
The other person disagreed and said people will have to go back. If they don't too much of the city economies will collapse which will affect the overall economy (i.e. no coffee, lunch, rail tickets, cleaners etc) that it would be catastrophic.
I'm guessing that businesses will be forced to change, but maybe not? Am I being unreasonable to assume that all the people now working from home will be doing so permanently?
