One of the important challenges of organizational behavior is bullying in the workplace. The aim of the present study is to describe, analyze, and combine the analyses presented in the field of variables related to bullying in the workplace, and the meta-analysis method was used. The statistical population of this study included all scientific research articles and thesis available on the IranDoc website in Iran from 2011 to 2014. Among the studies conducted, 16 studies were selected for review based on the inclusion criteria. The data from these 16 studies were statistically analyzed based on the Pearson r correlation coefficient and the t-statistic for the Hedges' g fixed and random effects model. All statistical analyses were performed using CMA2 software. The findings showed that the average overall and combined effect size for the fixed effects model was 0.07 g=0.05, which was significant (P<0.05) and for the random effects model was 0.10 g=0.05, which was not significant (P<0.05). Therefore, the average effect size of the factors cannot be interpreted. Among the 48 factors identified, the discriminant effect size of 45 factors was significant. The factors that have the greatest impact on workplace bullying (P<0.05) include authoritative leadership (g=-1.28), demand balance (g=-1.01), fairness (g=1.01), excessive self-interest (g=1.44), contextual factors (g=1.56), jealousy (g=1.35), moral climate (g=-1.96), and moral leadership (g=-1.13).
