I think the only people claiming that remote workers slack off are the one's who slacked off themselves. Remote work existed for many of us pre-covid. I put it in more hours a week than I care to. Being a global resource, I'm on calls starting at 5AM, and as late as 9PM. A commute, along with trying to find a free desk everyday, would cut into my productivity, not add to it. Not to mention, not a single person I work with is located in my "home" office. Stop trying to frame remote workers as lazy, all it does is show how YOU likely acted during your COVID WFH days.
Exactly what @ept+1sPRVQug said.
