This script is intended as an introduction to the fundamentals of labor law. Knowledge of how an employment contract is formed, in which cases an employee can claim wages even without work, what liability standards apply in company-related activities, and under what conditions both ordinary and extraordinary termination are permissible is required not only from law students but also from students of business or social sciences. Those who wish to consolidate and deepen their knowledge acquired from this script through case studies are recommended to refer to the script "Standard Cases in Labor Law" published by niederle media. The name niederle media stands for scripts largely authored by writers with several years of teaching experience as university lecturers or group leaders, presenting exam-relevant topics in a concise manner.
