Abstract
This paper tackles the current challenges to private sector unionism in the United States in
light of Catholic social teaching (CST). The focus of the study is unionism in the private
sector where the fall-off in membership is observed. CST is contained in a wide variety of
official documents of the Catholic Church, in particular papal encyclicals, which present
ethical norms for economic life in response to the changing realities of the modern world.
The study begins with an analysis of the concrete situation: the causes of decline in union
membership. It is followed by an ethical reflection on CST’s perspectives and exploration of
practices, strategies, and policies that can help reverse the ongoing trend of union decline
and revitalize the labor movement in the country. The paper argues that unions are good in
themselves as an expression of the workers’ right to associate and instrumentally good as
they invoke such values as the dignity of work, solidarity, subsidiarity, common good, and
economic equality. While it has been proven that workers and society as a whole gain
material benefits from effective unionization, focus on intangible benefits and moral
principles offered by CST may give labor organizing a new impetus and inspiration.
