The only times I see this happen is upon completing a Quest Location like the wolf hunting quests that feature a single battle and immediately sends everyone back to the mansion upon resolution. I actually consider this a feature as it saves me time reassigning everybody to their prior jobs (many I do not remember what my plans were in assigning their duties in the first place). The current system for everything else of resetting back to default resting is just a pain in the neck where I have to remember who was doing what and why, often without clues of gear.

Every Now and then, I have my main character do jobs like "Spell slinging" for example, but by mistake, I had them cooking when I meant for daisy to do that. So instead of resting and recovering a significant ammout of mana and health, I was just going through the motions, and went into a dungeon with less resources than I thought I had. Wound up costing me a good hour of progress, but I understand that's my fault.
