In the consultancy company I work for, 99% of us are now working from home. All this was done in a very few days. On the evening of Friday 13 March, I was still thinking of going to my client's office, but only on Monday to facilitate the logistical aspects of a full day's meetings.
But overnight, confirmation was received that I should only go to my client's office if absolutely necessary. So the logistics will pass! It's the evening of Tuesday, March 14th when I write this article, and the episode I'm living and sharing with many of us is just beginning. However, I think there will really be a before and after these events.
