The continuous natural depopulation that has been going on in Croatia since 1991 has a negative impact on the pension system and the labor market. The increasing share of the elderly population in the total population calls into question the sustainability of the pension system in the future. Therefore, it is very important to emphasize the importance of saving for old age to younger generations. By introducing the third pension pillar, which represents voluntary pension savings, the state wants to involve as many individuals as possible with incentives. The Croatian labor market is characterized by low employment rates, a mismatch between supply and demand, low wages and a lack of labor. Joining the European Union opened up the possibility of free movement on the labor market within the European Union, which encouraged an increasing number of emigration, especially of the younger population. In this way, Croatia is losing its young and educated workforce, which is the engine of economic development. By amending the law on pensions, the government enabled part-time employment for pensioners without suspending their pension, thereby providing them with an additional source of income, and employers with an additional source of labor. Pensioners are becoming an increasingly important factor in the labor market. During the preparation of this paper, a survey was conducted using a short questionnaire and an in-depth interview, the purpose of which was to investigate the motives and attitudes of those who are about to retire and those who have already retired to stay on the labor market with a pension. The results of the research showed that financial reasons are a key factor in employment in addition to pensions, followed by work habits, and that pensioners are the most represented in trade activities. Also, the research showed that retirees are satisfied with their current job and that they work even more than the prescribed number of hours.
