Purpose of the work is to investigate theoretical principles of employees’ rights protection in the context of responsibility for mobbing. The theoretical and methodological basics of the research are general scientific and special methods of certain jurisprudence phenomena and processes’ cognition. The dialectical method was used in the synthesis of theoretical and methodological foundations of employment policy abroad and in Ukraine, as well as formulating conclusions. Thus, we used a common dialectic method which allowed us to reveal the content of employer, employee and mobbing in the context of the domestic and foreign scholars’ experience. We also have used abstract and logical investigation methods of law process in the field of employee’s rights protection. Statistical methods were used for analyzing trends of employee’s rights in different countries.
