Background: Work-family conflict is one of the human being issues that may be inevitable. The 
overlapping of home and work roles could interfere with the roles at home or cause problems at 
work. These conflicts have a negative impact on job performance. Nurses who are proficient in 
practicing emotional intelligence had a better capacity to handle stress and job performance. Aim:
It was to assess work-family conflict and emotional intelligence in relation to job performance of 
staff nurses. Subjects & Methods: A correlational descriptive design was conducted on staff 
nurses (270), who answered a questionnaire measuring work-family conflict in addition to 
emotional intelligence, whereas their job performance was evaluated by their head nurses using an 
observation checklist. Results: The highest percentages of staff nurses had a moderate level of 
work-family conflict and a high level of emotional intelligence, and 59.6% of them had a good 
level of job performance. Job performance had a statistically significant negative correlation with 
work-family conflict which had a statistically significant positive correlation with emotional 
intelligence. Conclusion: Job performance is negatively affected by work-family conflict. 
Emotional intelligence has a larger effect size than work-family conflict on job performance among 
staff nurses as emotional intelligence has a large effect size on their job performance compared to 
the moderate effect of work-family conflict. Both of them have a low effect size on each other. 
Recommendations: Training staff nurses targeting job performance skills improvement besides 
work-family conflict management and how to use the high level of emotional intelligence ability to 
improve are recommended.
