It adds up when you have a lot of meetings where you need to do that. Also 2 to 3 hour commute is insane. And I'm not suggesting office work needs to be 5 days a week. Also the type of work really makes a difference as well. I'm also not sure wfh is more efficient. In the in office days meeting room availability dictated the number of meetings you could have a day. Virtual has created meeting hell for me at times.
