This study aimed to describe the relationships between leisure satisfaction, job performance, and life satisfaction among private-sector employees. The study sample consisted of 347 employees, 158 males, and 189 females, working in a private company in Istanbul. The participants were selected using a purposeful sampling method. The data collection tools included the "Leisure Satisfaction Scale"; the "Job Performance Scale", and "Life Satisfaction Scale". The data were analyzed using independent t-test, ANOVA, MANOVA, and Pearson Correlation analysis. The analysis results showed no significant difference between the Life-SS and Leisure-SS scores by gender, but there was a difference in the JPS scores. No significant difference was measured in any scales by marital status. There was a significant statistically meaningful difference between the Life-SS and JPS scores by working types, but no difference in the Leisure-SS scores. There was a difference between the Life-SS and JPS scores; the difference in the Leisure-SS scores was not significant. There was a positive and low-level relationship between JPS and Life-SS. Similarly, a positive and low-level relationship was found between the "Psychological," "Educational" and "Social" sub-dimensions of Leisure-SS and Life-SS. However, there was no relationship between the sub-dimensions of JPS and Leisure-SS. In conclusion, there were meaningful differences in all scale scores by specific socio-demographic characteristics; there was a positive correlation between the "Psychological," "Educational" and "Social" sub-dimensions of Leisure-SS and the Life-SS, and that there was no relationship between Leisure-SS, Life-SS, and JPS. As a result, it can be said that as individuals' job performance and leisure time satisfaction increase, their life satisfaction also increases.
