Last day at the worksite is the last part of the country road quest. If you have trouble on how to trigger this event, I can paste that part, but the ingame guide should be sufficient.
Why did you feel the need to write "For the Bareshade expansion quest, I chose the Fair -> Watchmen -> Houses order,"? (It's not a derogatory question, I just want to check if, as I though, simply copying/pasting part of the guide is not enough to answer some questions)
