You're quite right Ufddd. It could be, and will be, inconvenient at best, difficult for many, and well-nigh impossible for scores of ordinary working people.
SWMBO has been working from home since 23rd March. We don't have an office or dedicated "computer space", so she's operating from the dining room table. She printed off a works document the other day, 32 pages, and ran our printer out of ink......
She's spending all day on a dining chair at that table. It's not good for her back, not having a proper office chair, but at least she doesn't have to get up early to do the (very unpleasant and tiring) commute into London. Given her normal office hours of around 38 hours a week, there's at least another 20 hours to be added commuting - and out of hours calls if something happens in the 24/7 place where she works. So at least 60 hours a week working.
Now, she's doing an 8 hour day 5 days a week. She's cashed in her Season Ticket, which costs her over £300 a month (after tax remember), and if she does have to go into the office occasionally, she'll just pay as she goes - and that'll be outside the rush hours.
So she's better off financially, has more time at home, but oddly, less freedom. Now she has to have a conference call in the morning with some of her staff, another conference call with her Boss and the other department heads mid-morning/early afternoon, and another conference call after that with the rest of her staff to report results of the earlier calls. That's a bit of a *&%^$ for me, as I either have to stay quiet, or make myself scarce whilst these "Teams" or "Zoom" meetings are in progress. And not distract her if she's typing a sensitive document to e-mail.
Therefore, her working from home impacts my life differently than it did when I dropped her off and collected her from the station, but had the whole of the day to myself. But on balance, despite the inconvenience and/ or minor difficulties, working from home is preferable - for her. It won't be for everybody of course, but anybody flogging into work every day, some distance from home, will welcome the respite working from home brings - despite any resultant problems.
I was just making the point that post COVID-19, our world will have changed, and those changes may be irrevocable. And many of the changes will have consequences and impacts unforeseen at the moment.......
