Background and Purpose:People spend a significant part of their lifespan working, but the role of age in job design and implementation of work have largely been ignored. The consequences can be evident in stress and burnout in different symptoms. Thus, age-diverse employees are faced with different symptoms of burnout and stress when carrying out their work. The main aim of this paper is to present burnout of older employees compared to younger employees in Slovenian companies. Design/Methodology/Approach: The paper is based on research including a survey between two age groups of employees, namely the younger employees that were classified in the group of under 50 years of age and the older employees that were classified in the group of above 50 years of age. Since the Kolmogorov-Smirnov and Shapiro-Wilk test showed that the data was not normally distributed, the noan-parametric Mann-Whitney U test was used to verify differences in the physical symptoms of burnout, emotional symptoms of burnout, and behavioral symptoms of burnout in the workplace between two groups. Results: The results show that there are significant differences in the great majority of the variables describing the physical symptoms of burnout, emotional symptoms of burnout, and behavioral symptoms of burnout in the workplace between younger and older employees. Conclusion: Well-being in the workplace of age-diverse employees is a key for long-term effectiveness of organizations. Managers and employers should apply appropriate measures to reduce burnout as well as to contribute to employees well-being and better workplace performance.Keywords: Physical symptoms of burnout, emotional symptoms of burnout, behavioral symptoms of burnout, employees, human resource management 1
