Pope John Paul II
On Human Work #49, 1981
“Workers have the right to form associations for the purpose of defending their vital interests…The experience of history teaches that organizations of this type are an indispensable element of social life, especially in modern industrialized societies. Catholic Social teaching…hold that unions are…indeed a mouthpiece for the struggle for social justice, for the just rights of working people in accordance with their individual professions…It is characteristic of work that it first and foremost unites people. In this consists its social power: the power to build a community…It is clear that, even if it is because of their work needs that people unite to secure their rights, their union remains a constructive factor of social order and solidarity, and it is impossible to ignore it.”
Pope John Paul II
Centesimus Annus, 1992
"…The freedom to join trade unions and the effective action of unions…are meant to deliver work from the mere condition of ‘a commodity’ and to guarantee its dignity. “…The right of association is a natural right of the human being…Indeed, the formation of unions cannot…be prohibited by the state because the state is bound to protect
natural rights…”
Pope Pius XI
Quadregesimo Anno, #83, 1931
"For as nature induces those who dwell in close proximity to unite into municipalities, so those who practice the same trade or profession, economic or otherwise constitute as it were fellowships or bodies. These groupings, autonomous in character, are considered if not essential to civil society at least a natural accompaniment thereof."
Pope John Paul II
Centesimus Annus, 1992
“Trade unions…serve the development of an authentic culture of work and helps workers to share in a fully human way in the life of their place of employment.”
Vatican II
The Church and the Modern World, #68, 1965
"Among the basic rights of the human person must be counted the right of freely founding labor unions. These unions should be truly able to represent the workers and to contribute to the proper arrangement of economic life. Another such right is that of taking part freely in the activity of these unions without fear of reprisal."
