Quite the opposite. Several divisions in my organisation and others in our group have decided to gradually move to a model where about half of us work from home for the medium term, and that number is expected to increase over the next five years. They are already saving a significant amount of money by giving up our old offices. The mode of engagement between staff and across teams has obviously changed and continues to do so, but productivity is back to pre-Covid levels. We meet in person when there's a real need, say once a week or two. Even allowing for the possibility that the contents of the article are true (which I seriously doubt ... it reads like sloppy reporting and cheap sensationalism) this is one man's view, biased and coloured by his own interests.
