The prison system is a very complex system, and the fact that work in prison is one of the most difficult is often highlighted in the literature. Namely, the prison staff has the task of taking care of the prisoners, while taking care of their safety as well as their own. Also, it is necessary to treat every prisoner in a way that respects his specificities, wishes and needs, respecting all his rights. Therefore, every prison employee, depending on the domain and powers, must be focused, primarily, on achieving the goals of serving the sentence, but also on reducing the harmful consequences caused by life in prison. In doing so, the most important thing is that each prisoner is treated humanely, with parallel respect for his dignity. In this final paper, in addition to the theoretical basis, statistical data of the Croatian prison system will be presented with the aim of reaching a conclusion about the functioning of the same. Also, a brief overview will be given of the available data on the number of prisoners and employees in the Penitentiary and Prison in Šibenik in 2022.
