Background: Internal work coalition is favorable when a group of nurses come together for the purpose of gaining more influence and power which positively affect their work outcomes. The study aimed to assess the relation between internal work coalitions and nurses' work outcomes. Design: Descriptive correlational design was utilized to conduct this study. Setting: The study was conducted at all inpatients units of medical and surgical departments at Benha University Hospital. Subjects: A simple random sample of 317 out of 1539 nurses working at the previous setting. Two tools were used for data collection: (I): Internal work coalitions questionnaire and (II): Nurses work outcomes questionnaire. The study results showed that more than half of studied nurses (50.8%, 53.9%) reported moderate level of internal work coalitions and nurses' outcomes respectively. Conclusion: There was highly statistically significant positive correlation between total levels of studied nurses' internal work coalitions and their work outcomes. Recommendations: Paying more attention to the vital role of the internal coalitions as a valuable strategy for upgrading nurses' cooperative abilities improving their work outcomes.
