Background: Nurses who experienced fair treatment from their employers were inclined to demonstrate increased dedication, stronger trust in their organizations, higher job satisfaction, reduced intentions to leave, and exhibited positive and ethical conduct in their workplace. Aim: To explore the relationship between organizational justice and lateral violence among staff nurses. Design: Descriptive correlation design was used. Setting: The current study was carried out at multiple departments of Cairo University hospitals. Sample: A convenient sample of 100 staff nurses was selected from the aforementioned setting. Tools. Two tools were used: Tool I: Organizational Justice Scale among staff nurses that consists of two parts. First part: Nurses' personal data. Second part: Organizational Justice Scale. Tool II: Lateral Violence Scale among staff nurses. Results: 55% of the staff nurses had a low level of perceived organizational justice, and 41% of them had a high level of lateral violence. Conclusion: There was a statistically significant negative correlation between total nurses' perception of organizational justice and lateral violence. Recommendations: Providing training opportunities for nurse managers about fair management strategies for their staff nurses. Healthcare organizations should counter any form of lateral violence through regulations and disciplinary actions.
