this study investigated the moderating effect of workplace social support on the relationship between leader–subordinate fit and entrepreneurial behaviour in an Iraqi private higher education institution. A sample of 127 respondents was selected and a questionnaire was administered to them via Google Form. The data thus collected were analysed using JASP. Consistent with the P-E fit theory, the results revealed that supplementary fit (β = 0.44, t = 6.65, p .001, 95%CI = 0.29 to 0.53) and complementary fit (β = 0.46, t = 6.91, p .001, 95%CI = 0.31 to 0.56) significantly predicted entrepreneurial behaviours. However, in contradiction to the buffering hypothesis, the semi-partial Bayes Factor (BF) statistics indicate that workplace social support did not play any moderating role in the model. The study concludes with a brief discussion on the results, limitations of the study, and suggestions for further research.
