This isn't meant to diminish the difficulties of people who need to look after their children. But I work in a laboratory where the senior people blithely complain about how hard it is to manage shared child-raring duties in a well-equipped home office, while junior employees are more or less expected to magically have a productive home office in a shared flats, often in less-than-ideal environment (e.g. with noisy room-mates or building sites next door), with RSI staring us down.
Definitely? I have no kids and live with and fully support my father who had a brain tumor the size of a walnut in his head a couple years ago. Just because someone doesn't have kids doesn't mean they don't have responsibilities (goodness so many negatives in one sentence!).
If my office was 10 min walk away I would not want to work at home, but it is 1h by car ...
The evidence shows that WFH work creep is a thing - you get people who dont know how to turn off, and bosses who think they can get more out of you since you are a few feet away from your laptop.
There is also a decrease in creativity and networking - evidence again shows that a good team has someone who is very tuned to the emotional and mental states of the people around them doing a lot of bridging.
Finally - the people who work at office get more money over time, unless the firm takes active measures to combat these biases.
