The purpose of the research was to analyzing the role of employees' slacktivism in organizational isolation (OI) with emphasis on the mediating role of self-presentation (SP) and organizational silence (OS). This research was applied in terms of purpose and survey-causal in terms of the nature of the method. The statistical population was all the employees of the executive bodies of Ardabil province. Considering the size of the population, which according to the latest statistics was about 40,000 people, the sample size was determined to be 380 people using Cochran's formula, and the selection of these people from the population was done by simple random method. Data collection was done through four questionnaires. Validity was confirmed by confirmatory factor analysis and reliability using Cronbach's alpha. Data analysis was done by SEM method and using SPSS 26 and Smart-PLS 3 software. The findings showed that since the t-value is greater than 1.96 at the 95% confidence level and considering the path coefficients, slacktivism has a positive and significant effect on OI, SP and OS. Also, SP has a positive and significant effect on OI. In addition, OS has a positive and significant effect on OI. Also, since the Z-value is greater than 1.96 at the 95% confidence level and considering the path coefficients, SP and OS plays a mediating role in the relationship between slacktivism and OI. The results lead organizations to make more efforts to reduce the slacktivist behaviors of their employees in order to prevent organizational isolation in them.
