Chuck Tents are Infrastructure buildings in Tropico 2 that provide food for captives. It requires corn, which it turns into slop. It's important to provide enough Chuck Tents in relation to the number of captives. Having too few of these causes several problems. It's better to have too many than too few. A good rule of thumb is to have one chuck tent for every 30 captives. If you find that your chuck tents are lacking in corn, it may be necessary to build additional Corn Farms.
Having too few Chuck Tents prevents captives from satisfying their hunger. This will eventually cause them to starve to death if the problem is not mended, as well as lowering captive resignation.
