Seriously, I can't be the only one who is just slacking off when working from home.
I slack off in office for a similar duration that I do at home. They might be different but the "productivity" is identical if not favoured at home because I'm more comfortable. I'll spend time configuring my nvim or reading some interesting but unrelated technical article/book or getting snacks or HN or reddit in the office. At home I might just take a nap or shower or go to the gym (or do one of the aforementioned things).
People operate differently but for me I'm only going to produce as much value as I believe I'm getting paid for. Not more and not less. I see the request to go back to office as managers believing they can act as a coercive force which might work on some (perhaps many) people.
