Workers are a caste of cho-ja society. They are either clever or strong.
The strongest of them are shorter, stockier, and more placid in demeanour than the cho-ja soldiers. They are miners, carriers, suppliers, or beasts of burden according to the needs of the hive.
The cleverest of them are more agile yet less formidable than the warriors and become artisans. These can make silk and jewellery of exceptional beauty.
They also feed or tend the cho-ja queen, preening her enormous body, attending diligently to her every comfort and need.
