STRINGS.MISC.NOTIFICATIONS.TASKPRIORITIESMESSAGE.MESSAGEBODY
Duplicants always perform errands in order of highest to lowest priority. They will harvest Food before they build, for example, or always build new structures before they mine materials.
I can open the Priorities Screen {Hotkey/ManagePriorities} to set which Errand Types Duplicants may or may not perform, or to specialize skilled Duplicants for particular Errand Types.
