Modern organizations seek to recognize the impact of stress and job dissatisfaction on the quality of their employees work. This paper described the concept of stress at work and its impact on work satisfaction. In the empirical part, a survey of 49 Pension Insurance employees was conducted in order to determine which sources of stress at work they perceive as the most intense. Different categories of Pension Insurance employees in Zadar (men and women, who would change jobs and those who would not) were distinguished in the perception of stress of different work stressors. The job is on average estimated from medium to very stressful. More than half of the respondents would leave their jobs if given the opportunity. The most intensive stressors were the extent of work, monitoring of frequent changes in the law and deadlines. Some gender differences were also found, where they showed that 63% of men would change jobs if they could, while 52.63% of women would change jobs if given the opportunity. Those who would change job perceive more stress and have greater job dissatisfaction, than those who would not change the job. The results indicate the need to reduce the extent of work and better organization of the work process.
