Correct on both statements. And that is what I deal with every day. If I can't see you, you must not be working and it doesn't matter that the work is actually getting done. I understand there are always those who abuse the privilege, but that is on management to fix. And if management IS the problem, then the execs are to blame. I work for some yes men(women) who will agree to whatever they are told by the execs because they just want to keep that fat check coming in without regard to if what they are agreeing to is the right thing to do.
When I lived in Cali and worked for the San Francisco VA, I requested to work from home for a few days a week to reduce a bit the hellish commute, and was denied, “because everyone knows that people working from home just drink all day.” * (I mean, my boss said that to me, face-to-face,verbatim.)
So a few years later, I transferred to Asheville VA with a fancier job title (and job), and after two years requested to work from home X number of days a week, because I was a data-cruncher, and no one wanted or needed to visit with me in person (I mean, I am an INTP, and NO ONE wants to visit with me in person

), but was denied, because “OMG, what if Dr. Whosiwhatsit needs to meet with you?” (Note: I have a phone, and a car.)
So then, the original “you’ll drink from home” SF VA boss calls me and begs me to come back - but working remotely, mind you - because they need my expertise. OK, fine, here I am in my Asheville Eastern Time Zone dining room, logging into San Francisco, and doing my job, including often calling in after hours for Fancy Meetings. Oddly, my same boss was now able to manage me from three time zones away.
So after a year or so of this, my mother had her Big Fall and Eventual Consequences, and after many months of bunking on hospital beds and whatnot while working even-more-remotely (successfully), I said eff it and retired. (But then I worked as a contractor for another year or so, because hey, that’s what we do.)
And 6 months after getting The Hell Out of Dodge, COVID hit, and hey, everyone went remote, and the world kept on turning. Go figure. They did use my profiles and experiences to successfully set up access for the rest of the staff. <pauses to admire this IT flexibility> My you’ll-just-drink-from-home boss somehow took a break from his all-day-every-day video game habit to note that work kept getting done just fine.
* Note: there does seem to be something to this “working from home/ drinking all day” thing, but in my experience, it actually doesn’t kick in until maybe 4:30-4:45 or so. Depending on the day of the week. Well, sometimes 3:30, but hey, I’d been on since 7!
