The document discusses the Catholic view of the dignity of work and rights of workers. It traces the development of this teaching from biblical sources through modern papal encyclicals in response to issues facing workers. Key events that shaped the teaching include the Industrial Revolution, Great Depression, and fall of communism. The Catechism affirms the dignity found in work as participation in God's creation. Over time, Catholic social teaching has supported workers' rights to organize and affirmed principles like subsidiarity and the priority of labor over capital.
