Working conditions, too, differ between rural and urban areas. Farmers rely on family members, including small children, to help labor in the fields and harvest the crops. Animal herders have a different lifestyle, migrating seasonally between northern and southern pastures. Monetary wages are low for unskilled workers, averaging less than a dollar per day. More educated workers can earn substantially more, but the scarcity of jobs tends to drive down wage rates. Chad's labor code is adapted from French laws that are protective of workers, but workers in the informal sector are not covered by these rules. Several unions have been formed to represent different workers, but their influence is limited.
