It works extremely for my husband and me.
I have a role that has always worked well remotely. I wfh 1-2 days per week pre pandemic.
The office was always too distracting, groups of colleagues, chatting all day, phones going, too hot, too cold, office politics. I have always been more productive at home.
DH started wfh in the pandemic - we both have different rooms - and he saved on 3hrs of commuting a day. He's due back in the office 2 days a week, because those who chose to go back are asking when everybody else is!
At my work, there are some people who also choose to go in, either because their particular roles don't work at home, they don't have space, there are small kids (grandkids) at home, or they simply prefer it. Most of these though are the workers who - even before the pandemic - like to socialise at work, and chatter all bloody day, go out for lunch etc. All had never wfh pre pandemic and said they prefer office work. Fair enough.
Their return is up to them, but they are now threatening to spoil it for the rest of us, asking when others will return. Deliberately asking those of us who do prefer wfh on Teams calls if we're still wfh (er yeh, I'm on a Teams call with you).
It's not fair on those of us who have quiet spaces, who are fine working remotely, who don't need to socialise at work, and who have wfh for years. These are not young people by the way - these are women, like me, in their 40s/50s.
There seems to be a culture/mindset still that being seen at one's desk is a measure of productivity. And a culture that if you can't/don't want to wfh then nobody should. The irony is, that when I was in an office with those workers, they spent all day nattering and I could not focus.
