This article aims to analyse the prohibition of mobbing in labour law in the context of contemporary legislative changes and its axiological foundations rooted in Catholic social teaching. The reference point for the study is the encyclical Laborem exercens by John Paul II, which formulates a personalist concept of work as a space for the realisation of human dignity. The paper seeks to answer the question of whether the planned regulatory changes constitute a genuine reform of employee protection or rather require a deeper reinterpretation in light of the values underlying labour law. The author advances the view that the effectiveness of anti-mobbing regulations depends not only on their normative content but also on their axiological grounding.
