This study is based on a meta-analysis, conducted in Turkey between the years 2012-2020, that focuses on the psychological capital (PsyCap) and burnout sub-dimensions'relationship of employees working in both public and private sectors. The analysis was carried out based on the correlation coefficients and sample sizes of 9 studies with a total sample size of 2280 that complied with the previously established criteria. After the stages of literature review and coding, calculating the effect sizes of each studies that meet the criteria, performing basic meta-analysis and calculating the general effect size, estimation and correction stages of publication bias were carried out with Comprehensive Meta Analysis (CMA) V3 software. The general effect size was calculated through the random effect model as a result of the homogeneity test. Additionally, it was concluded that there was no publication bias by examining the funnel plot, fail-safe number and Tau coefficient. According to the results of analyzes, all hypotheses claiming that there is a negative relationship between employees' psychological capital and burnout sub-dimensions working in Turkey were proven. It was revealed that the general effect sizes under the random-effect model varied between weak and medium levels. These results have been discussed within the scope of the literature, and suggestions have been developed for practitioners and future studies.
