Agreed. Especially with less experienced folks, remote work can be hard because there's less context. You can't see someone struggling quietly at their desk, they have to ask for help or you have to ping them.
At a butt-in-seat job, I'd turn up on time and leave on time - and that's the end of it. If during those hours I happen to be in an unproductive mindset (eg, unable to concentrate) then so be it. I'm paid for my time. If I happen to be in a productive mood after hours, their loss.
Now that I'm working remotely, if I'm feeling unproductive then I will stop work and do something else (shopping/walk/etc.) and resume when I'm more productive.
I also don't mind being contacted out of hours (I'll decide if I'm busy or not) - they're flexible with me, so I'm flexible with them.
They'll get the same number of clock-hours from me, but with more work output.
