The analysis was carried out on the basis of selected division criteria, which included: the patient’s age and gender, the province in which the patient lives, and the disease unit on the basis of which the e-ZLA form was issued. The research was conducted for the year 2020, due to the fact that it was a full pandemic year and because the identification and analysis of sickness absenteeism in unusual, uncertain, and unpredictable situations is extremely important for maintaining and developing the competitive position of companies and for maintaining a sustainable policy in the sphere of health and social insurance.
