AIBU To Think Remote Work Isn't Sustainable?

I think hybrid is the best balance . There’s a lot of positives to being in an office and also being at home . I did hybrid and not commuting was the biggest plus on my wfh days . The biggest ballache was not being able to get hold of other wfh personnel because they were setting their own day around other goings on at home , taking the kids to and from school . Office based is definitely best for young people and new starters learning the ropes . WFH works best for those proficient in their role but also jobs not related to being available at certain times , it’s very frustrating doing a piece of work needing someone’s input to find them not at their desk and no idea when they will be .

It might not be sustainable for you but many are happier and more efficient working from home because commuting can be time consuming. Many would also say that chatting on Teams is talking about work?
I work in a job that can’t be done from home so understand that you can’t use Teams for chatting about non work stuff as work will be monitoring but many don’t want to gossip or hear about their colleagues’ lives out of work which is fine too.

I wfh in two jobs and I am very happy most of the time. I see enough of people in video calls. I don’t need to see anyone in person for work. I’ve been doing this for 9 years so clearly sustainable.

You’re speaking from such a narrow view point I don’t know why you bothered. I wfh pretty much 100% and am almost constantly in meetings, talking all day.

I don't know if "not sustainable" is the right way to describe it, but I do agree that 100% remote working isn't healthy for most people. Convenient, yes sometimes. I think homes and work should be separate (it drives me mad that a whole room in our house is set up for my dh's work and I can't go in there for much of the day) and that most, not all, people need some human social interaction. When I was younger a lot of my social life stemmed from work - it was fun! You also get to negotiate relationships with people who are a lot older or younger than you, from different backgrounds etc.

I've been doing it for 13 years.

Tell Nigel to bore off to Dubai or wherever this "man of the British people" actually lives.

It might not be sustainable for you. But it is for many others. If you're not happy there are plenty of jobs where being in the office is compulsory.
