Quadragesimo Anno §34

³⁴ These counsels and instructions of Leo XIII were put into effect differently in different places according to varied local conditions. In some places one and the same association undertook to attain all the ends laid down by the Pontiff; in others, because circumstances suggested or required it, a division of work developed and separate associations were formed. Of these, some devoted themselves to the defense of the rights and legitimate interests of their members in the labor market; others took over the work of providing mutual economic aid; finally still others gave all their attention to the fulfillment of religious and moral duties and other obligations of like nature.
