Abstract
The author presents the view that collective labour law values are, inter alia, derived
from the achievements of the social doctrine of the Catholic Church. One of such values
is the common good. John Paul II refers to it many times. According to Him it is a personal
value that liberates from selfishness and vested interests. The essence of collective labour
law is based on a sense of the common good category, understood as a right expressing
a compromise between different interests. Means to implement that common good which
leads to social peace is a social dialogue. There are many regulations aimed at a social dialogue,
in particular, the provisions specifying the procedure for conducting negotiations
in order to conclude a collective agreement.
