Recently, another part of the Labor Law System has been published – the thirteenth chronologically and the twelfth in substantive order. The reviewed volume is devoted to administrative-leglal employment. The study proves the validity of the thesis that service relations law is the domain not only of administrative law, but also of labor law. For the first time in Polish legal literature, the subject of administrative-legal employment was presented so comprehensively. The elements of the service relationship, the relationships functionally related to it and the social provision system for officers and professional soldiers were presented comprehensively and mostly in depth.
