A lot of people pushing for full-time WFH. Let's not kid ourselves by claiming we're more productive at home. especially if you have kids. Other distractions: telly, PS5/ XSX/ Switch, interactions with housemates/ pets (instead of interactions with co-workers in an office environment). And a lot of procrastinating - "I can do that later after dinner." "I'll just turn my laptop on and login while I go to the shops, cook, eat, nap and check OzBargain. They won't know the difference."
Don't give your boss an excuse to outsource your job interstate/ overseas or find another employee willing to work in an office environment. If you're boss/ supervisor/ superior is willing to rock up the office every day, what makes you think you're ok to WFH? Oh, you also want the same pay for WFH? What's that, you want a payrise?
