The Church’s position was initially laid out by Pope Leo XII in the encyclical Rerum Novarum in 1891. He saw unions as mutual assistance societies based largely on the old guild systems. He was speaking out against the efforts of some countries to outlaw private associations, specifically unions:
49. The most important of all are workingmen’s unions, for these virtually include all the rest.
- Private societies, then, although they exist within the body politic, and are severally part of the commonwealth, cannot nevertheless be absolutely, and as such, prohibited by public authority. For, to enter into a “society” of this kind is the natural right of man; and the State has for its office to protect natural rights, not to destroy them; and, if it forbid its citizens to form associations, it contradicts the very principle of its own existence, for both they and it exist in virtue of the like principle, namely, the natural tendency of man to dwell in society.*
It appears to me that the idea that Leo XIII was vindicating the existence of modern unions is overreach. He was careful about what he was allowing as his very next comment was this:
52. There are occasions, doubtless, when it is fitting that the law should intervene to prevent certain associations, as when men join together for purposes which are evidently bad, unlawful, or dangerous to the State. In such cases, public authority may justly forbid the formation of such associations, and may dissolve them if they already exist. But every precaution should be taken not to violate the rights of individuals and not to impose unreasonable regulations under pretense of public benefit.
Around the turn of the century, when unions were beginning, there was a need for them, section 51 (above) was the relevant passage, and I think local parishes strongly supported union activity. Times have changed but the perception of unions - historical inertia - has not. Now it’s time to focus a bit more on section 52.
