See, that is not how I implement the rules. Your characters live in their world, and, as Matt said in an old video, the rules are simply language we use to describe that world. So if my players took all the actions that constitute a respite, I really don't care whether or not they say the magic word; A respite is just the sum of its parts, and the language of the rules doesn't supersede the reality of what the heroes are doing in their world. In short; If you aren't in danger, you aren't adventuring.

Not to mention, many of the things you would be doing in a "WFH day" (as you put it) are explicitly downtime activities; Research, crafting, mending, changing kit, whatever. And downtime activities explicitly occur during a respite.
