Due to high workload, high pressure, and stress, the nursing job has been the basis of many studies to identify the effective factors related to this job. Job enthusiasm as one of the important issues of organizational behavior and in interaction with other relevant aspects including job resources has a special place due to its effects on organizational effectiveness. Therefore, the present study was conducted to determine the relationship between job enthusiasm and job resources in nurses. The current research was a descriptive cross-sectional-correlation study that was conducted on nurses. Data collection was done using a 3-part questionnaire, including the social profile of the participants, the job enthusiasm questionnaire, and the job resources questionnaire. To analyze the data, SPSS version 23 statistical software was used and descriptive statistics and analytical statistics methods were utilized. A level of 0.05 was considered statistically significant. The findings of the study showed that the level of job enthusiasm and the amount of job resources in nurses is average. The results also showed that there is a positive and significant statistical relationship between job enthusiasm and the amount of job resources of nurses (P < 0.05, r = 0.36). According to the findings of this study, the job enthusiasm of nurses is directly related to the lack of job resources, so with the increase of job resources, their job enthusiasm increases.
