We introduce a model that examines the relationships between organizational justice, leadership style, organizational citizenry behavior, and misuse intention. We hypothesize that ethical and charismatic leadership will increase organizational citizenry behavior and subsequently reduce misuse intention, while perceived organizational injustice will increase misuse intentions. We suggest that the existence of sanctions will moderate the relationships between perceived leadership and misuse. The relationship between perceived organizational injustice and misuse intentions are moderated by organizational security awareness and the Security Education, Training and Awareness program.
