WFH is nice, I’ve done it quite a bit but also never completely left the office or the area of the office so I was able to be there when necessary.
I’m a contrarian to this subject compared to the many who live it because they are receivers of benefit from it. What I see is more like Loaf From Home based on the number of couples and families out and about at all times of the day somehow justifying to themselves their absence from regular work hours. I have also managed people who are on their own and are supposed to be WFH, they start to justify a lot of things that just aren’t so like their productivity and attention to work.
In LFH relationships are killed, nuance is lost, convenience of sharing ideas and asking questions is gone, mentoring is absent and so is stimulation of the creative process by associations and none of this can be replaced by LFH.
All of this comes from someone who worked world wide and managed several virtual teams that were successful in delivering complex projects. One of the things I found essential was to plan for face-to-face opportunities even if it was a partially necessary meeting that included a meal and social gathering. I am an engineer not known for being a social butterfly but I think I can see what is necessary for people to be human and get the best effort from them.
LFH has its place but not always. I’m sorry for some to say that it is time to really go back to work.
However, I do have a co-worker who has issues working even when in the office. Being remote has, for him, turned into LFH, as you mentioned. It really is dependent on one's ethics and motivation.
