Generational differences are becoming an increasingly relevant topic in the contemporary work environment, especially in the context of changes brought about by globalization and digitization in a very short period. Considering that generational differences primarily influence attitudes, values, and expectations, it was interesting to explore how different generations perceive their work environment and how it affects their overall job satisfaction. By explaining the concept of different generations, such as the Baby Boom generation, Generation X, Generation Y, and Generation Z, as well as their characteristics, values, and attitudes guiding them in both private and professional life, it is expected that various factors and the fulfillment of different needs contribute to their job satisfaction. The focus of the paper is on generational differences and their job satisfaction, with a specific aim: the sample of respondents consists of civil servants within the state administration, which is quite legally framed in terms of human resource management. Thus, the range of benefits they can offer to their employees, both in material and non-material form, is quite limited. The research showed that there is no statistically significant difference between generations within the set hypothesis that generational differences affect the level of job satisfaction. However, this can be explained by certain shortcomings in the research (small sample size, uneven distribution of generations within the sample, and the absence of observation of situational factors).
