Assistant Professor explores Finnish labour law systematics which traditionally builds on a three-layered norm structure. The terms of the employment are determined by 1) legislative norms applicable to all employers and employees 2) provisions in collective agreements, and 3) individual employment contract terms. He argues that a fourth category of norms exists. These firm-specific group norms pertain to the relationship between the firm and its personnel or a personnel sub-group. The aim of Murto is to develop labour law theory to accommodate these norms into labour law systematic. The main research interest of Murto in the field of social law consists of transitional labour market and different transitions, especially questions related to lifelong learning. Murto’s publications include “Finish Basic Income Experiment in the Context of Finnish Social Law System” (University of Parma publication, forthcoming 2020).
