In the current era of digitalisation, enhancing the efficiency of legal regulation of employment relations and its application in practice is a pressing issue for legal scholarship and practice. This article analyzes modern concepts of legal application in the context of reviving the theory of labor relations. The author examines the essence and functions of the application of law and the main directions for improving the normative and legal framework in the labor sphere. The purpose of the study is to re-evaluate the mechanisms for the legal regulations of labor in the context of globalization, digitalization, remote, and platform work, and to rethink the subject matter and methodological foundations of labor law. The study comprehensively discusses the evolution of labor law, new forms of employment relationships in the digital economy (remote work, hybrid work models, platform work), and the specific features of their legal regulation. It is also based on the need to reconsider alternative dispute resolution mechanisms for labor disputes and the role of law-applying bodies. The article examines integrative, pragmatic, and human-centered approaches as modern concepts of legal application. These approaches are aimed at ensuring social justice in labor relations and increasing the effectiveness of labor law.
