The article discusses the implementation of the global concepts of smart city or smart municipality at the local level, focusing on the importance of mayor as a leader and his competencies in this context. The status of elected representatives of self-government in the branch of labour law is legislatively only marginally regulated, with insufficient terminological and functional interconnection between special legislation and labour law. The aim of the authors is to point out the relationship between the current legislation on prelegal relations between the mayor and his leadership duties and powers and to identify barriers in the implementation of the concept of smart cities in the Slovak Republic. The objective of the scientific study is determined based directly on current needs and emerging practical issues. Understanding and applying these correctly has a fundamental impact on the possibilities of rules in local government. Methodologically, our research relies on the basic methods of scientific abstraction in the context of the analysis of de lege lata legislation with a thorough application of the methods of legal logic. The authors draw attention to the partial questions of the labour status and educational census of the Mayor of the Municipality in the context of smart city concept and propose solutions.
