Purpose: This study investigates relationship between techno stress with job satisfaction of librarians in Ahvaz public libraries .
 
Methodology: The present study was conducted using a survey method and correlation analysis was used to examine the results. The statistical population of this study consisted of all librarians in Ahvaz public libraries in 1394, of which 71 were chosen as the study sample. The data gathered using the Ragu-Nathan techno stress scale (2008) scale as well as Minnesota's Job Satisfaction Questionnaire (1952). Data were analyzed using SPSS software using Pearson correlation coefficient and multivariate regression.
 
 
Findings: The results showed that there is a significant negative relationship between the constructivist factors of technological change, ie technology overload, technology influx, technology uncertainty, technology complexity and technological insecurity with job satisfaction of librarians. Also, the results of regression analysis indicated that there is a relationship between technology, technology overload, technology influx, technology uncertainty, technology complexity, and technological insecurity with job satisfaction of librarians. The complexity of technology was negatively the best predictor of job satisfaction.
 
Originality/ Value: This article shows with the increase in the complexity of technology, librarians' job satisfaction decreases, hence the expectations from the performance of librarians are not met. This highlights a need for technological training for librarians.
