This document discusses the concepts of work, compensation, and just wages. It defines different types of wages such as nominal wages, real wages, minimum wages, and living wages. It also outlines Catholic social teaching on providing a just wage, and factors that should be considered in determining a fair wage such as cost of living, laws and regulations, job factors, and individual performance. Some issues in defining a just wage are differences in local costs of living, interpreting fair pay for different jobs, and the influence of economic conditions like supply/demand and inflation.
