The Labour inspectorate of the Republic of Slovenia is an important administrative body, whose main purpose is the supervision of compliance with Employment Relations legislation, Health and Safety at Work legislation as well as Social Security legislation. The purpose of this dissertation was to determine which of the three areas is most problematic in terms of the established violations, what these violations are and whether the number of such violations decreases or increases over the years. The data for this dissertation was collected by analysing the Labour inspectorate's annual reports from 2016 to 2018, which include statistical data from different categories. In addition to reviewing the general information on the Labour inspectorate, this dissertation further examined the statistical data from the field of Health and Safety at Work, as it has been identified as the area with most irregularities. To further understand how inspections are carried out, this dissertation analysed five examples of inspections that were sent by the Labour inspectorate. The analysis results showed that most irregularities are indeed identified in the area of Health and Safety at Work, however most inspections are annually carried out in the field of Employment Relations. Based on the analysed figures from the Labour inspectorate's annual reports, this dissertation concludes that the Labour inspectorate of the Republic of Slovenia performs its job well within the scope of its capabilities. The issues with increasing the inspectorate's productivity occur as a consequence of a small number of employed inspectors, insufficient financial resources for any improvements and complex cases, which take a long time to be resolved and can continue for several years.
