In this research, the standard questionnaire of Hong et al. (2019), Kabiz (2004), Kalshon et al. (2011), Connelly et al. (2011) was used whose validity and reliability have been confirmed using the content validity method and Cronbach's alpha. In this research, structural equation modeling approach and SPSS and PLS software were used to investigate and test the hypotheses. The findings showed that ethical leadership has a negative and significant effect on knowledge concealment.
