The master thesis Work Values in Croatian Society between 1999 and 2018 includes theoretical and empirical research on work values in Croatian society over twenty years. Due to the historically dramatically different ideological and cultural influences in today's Croatia, it is not easy to determine what would be the key factors for understanding work and work values in Croatian society today. According to Ronald Inglehart's post-materialism theory, in advanced industrial societies, there is a cultural and institutional change in which economic growth ceases to be the central point of social development, and more emphasis is placed on the quality of life. The change in worldview and motivation is due to the fundamental difference between growing up in unfavorable economic conditions and growing up in economic abundance. According to the theory, individuals may have different motivations for work. In a society where material values are important, it will be important for an individual to have as much income as possible and a stable and secure job. In contrast, in a society where post-materialistic values prevail, meaningful and interesting work is more important. The goals of this paper are to analyze the trend of labor values in twenty years in Croatia; to compare the work values of the most recent year of the research with certain socio-demographic characteristics (gender, age, and level of education); and to compare work values of Croatia with the work values of the European Union, and also with selected EU member states that have higher, and others with lower living standards. Extrinsic and intrinsic work values were analyzed using data from the European Values Study from 1999, 2008, and 2018. After the analysis, we conclude that post-materialist values do not prevail in work values and that materialistic work values are the dominant factor of work at the level of European and Croatian society. However, concerning work values and socio-demographic characteristics in Croatian society, we conclude that intrinsic values are more important in the better-educated population, which aligns with the post-materialism thesis. Although we recorded higher extrinsic work values among the younger population, which is not in line with the post-materialist theory, we assume that Croatia is a specific case due to the relatively recent war and the economic crisis that occurred in the middle of the transition from a socialist to a democratic and capitalist system, which influenced a more positive evaluation of extrinsic work values in that population in their formative years.
