I am absolutely happy for the people I manage to stay home if they have real work to do. They can clearly do whatever they prefer, even work from the beach as far as I am concerned, but I know that going to the office is a waste of time. But the job we do is project based, long deadlines, no real “daily business” to handle. It however requires maximum focus, because it is not trivial. Offices are hells for concentration and quality work.
They can stay at home and call whenever they want whoever they want.
It has been working great.
It really depends on the positions. Office spaces are very bad for some positions, good fo others. Pushing a unique way of working for fishes and elephants cannot work. This is the main problem with current approach
