Unskilled Labor is an Era III technology which increases the amount of resources provided by Food, Industry, and Science Stockpiles by 500. It also enables the production of these stockpiles within cities via the Smokehouse, Warehouse, and Royal Academy constructions, which can be repeated indefinitely.
If Organized Labor has been researched, then these constructions will be replaced by those provided by Organized Labor.
Additionally, researching Unskilled Labor will increase the industry cost of the Pearls of Plenty, Pearls of Production, and Pearls of Wisdom stockpile constructions unlocked via the Pearl Hoarding Blessing by 500 .
Idle manpower can be used to stock conserved foods, industrial materials, and scientific equipment either for trade or for future use.
