Two things conflated here; 'compressed' hours and WFH. There's actually very little to connect them.
Five day's hours over four days works for some people. Given people's natural tendency to want either or both of Friday and Monday as non working days then, depending on the business's customers/clients there might be gaps. Dealing with things like that is why we pay managers. If that means some people working Monday and or Friday when that's sub optimal for them tough titty; maybe you swap shit patterns month and month about. We did that on one place as the service is 08:00 to 18:00 so you did a month one earlies 8-4 and then one on lates, 10-6.
WFH is a different thing. Until the pandemic it was 'impossible' in my sector. Then suddenly, when lockdown was a thing, a dozen laptops and mobile phones were found and a change that would have taken years of osmosis happened overnight. I've been either WFH or hybrid, the latter by choice, ever since.
In the middle of last month I moved to a new post; advice provision in a distributed call centre. The work is something I did from 2019 to 22 so I'm a returnee to the technical skills but telephone interviews/exploration I've done since God was a boy.
I wanted 24hours over 3 days and my offer to do those as Tuesday to Thursday was accepted without demur. As long as the service can run on Monday and Friday, something that can be managed centrally, those days are not my problem.
The supervisor has stuck to me like velcro for the last few weeks. She's listening on my calls and, via webchat and Google conference we catch up several times a day. Just like being in the office really except they're all but 500 miles away.
It's run by a national organisation but from local offices with an immense amount of freedom. Pre-pandemic you'd be working at an office in commuting distance. The one I'm working for now recruits across the UK; a much wider talent pool then along the east coast where they're based.
Horses for courses but WFH works brilliantly in my sector.
