I feel like most surveys on this topic are not going to be a reflection of reality. People are tired of being at home for a variety of reasons, including child-care difficulties and their inability to do much/any socializing outside the home, plus added COVID-related friction when doing normal chores like grocery trips.
These stress points make people associate these unrelated negative things with "working from home", which, in normal times, need not be quite the negative experience. Sure, there are valid reasons to prefer working in an office: lack of a workspace at home, desire for professional social interaction, desire to separate work life and home life, etc. But I think a lot of people who are so negative about working from home right now would be more positive about it if the COVID-related difficulties were removed.
I'd like to see this survey repeated, say, a year after things go back to normal (or as normal as they're going to get).
