In my experience there is a lot of resistance to this from the people at the top.
They have often risen to the top working in the old fashioned way of working, and don't feel comfortable letting go of the reigns.
Now many have been forced to during the pandemic it will be interesting whether there will be an attempt to pick those reigns back up and how the workforce will react to it.
I'm working mostly with people in China, Eastern Europe and the states at the moment, so it makes next to no difference whether I'm in the office or not, and I already have to keep unconventional hours.
Home working allows me to leave 30 minutes later when I have to pick the kids up to school, and get to work 30 minutes sooner after I drop them off. More time is available for work and I save on fuel costs.
My girlfriend doesn't work at all so the amount of sex during office hours has definitely increased (from 0)
so I can't claim to always be 100 focussed on the job (so to speak), but I think all things considered it works out better for me and for the company I work for.
Some things are always better face to face though. Once things seem more stable from a covid point of view I think I'll be trying to spend 2 days in the office and 3 days at home per week.
