The recent WFH has shown my daughter's firm that some management jobs aren't actually needed. They are on about evryone working from home in this region, with just one central office. No commuting yes, but also maybe a long journey to this one central office when you are needed.
WFH is not ideal for my daughter. She has a two year old toddler and an enthusiastic dog and getting quiet time to do your work can be a problem for her. Without family support it would be really difficult.
WFH will have a bad effect on the commercial property market. I can see a lot of office space standing empty in the near future.
There are upsides too, like the lesser commuting, better air quality and benefits for those who are disciplined enough to actually get their work done; but there are downsides too.
