Sampling was accomplished by census method. Job satisfaction was assessed using the JSS (Job Satisfaction Survey) in nine areas (Pay, Promotions, Supervision, Coworkers, Fringe Benefits, Contingent Rewards, Nature of Work, Operational Procedures and Communications). Data analysis was performed using SPSS 16 software. Descriptive and analytical statistics, including Fisher&#39;s exact test and Mann-Whitney test, were analyzed as well.<br> <strong><em>Results</em></strong><strong>:</strong> Most of the participants were female (69.1%), under 30 years old (48.7%), and with a bachelor&#39;s degree (75%). In general, job satisfaction of the majority of staff was moderate (75%). The mean job satisfaction in the areas of operational procedures (P=0.005), communication (P=0.027), and total score (P=0.042) in operating room staff was significantly higher than anesthesia staff; however, there was no statistically significant difference in other areas (P> 0.05).<br> <strong><em>Conclusion:</em></strong> Job satisfaction of anesthesia staff was lower in terms of operational procedures, communication, and total score; therefore, it is suggested that managers and authorities take this issue into account and take appropriate measures to improve the job satisfaction of staff in the mentioned areas. <div style="text-align: justify;"></div> job satisfaction, anesthesia assistant, operating room technician 47 53 http://nmcjournal.zums.ac.ir/browse.php?a_code=A-10-734-1&slc_lang=en&sid=1 Amir Hossein Gitifard Amirhosseingitifard137798@gamil.com 10031947532846007393 10031947532846007393 No Graduate of Bachelor of Anesthesiology, Department of Opertingroom-Anesthesiology Technology, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran seyede Fatemeh Gheiasi fatemeh.gheiasi@gmail.com 10031947532846007394 10031947532846007394 Yes Ph.D student, Department of Opertingroom-Anesthesiology Technology, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Vahide Karimi Karimiv88@zums.ac.ir 10031947532846007395 10031947532846007395 No MSc, Instructor, Department of Medical-Surgical, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Soheila Rabie Siahkali Rabie2@zums.ac.ir 10031947532846007396 10031947532846007396 No MSc, Instructor, Department of Opertingroom-Anesthesiology Technology, School of Nursing and Midwifery, Zanjan University of Medical Sciences, Zanjan, Iran Fatemeh Rafiei F.rafiei87@yahoo.com 10031947532846007397 10031947532846007397 No PhD student, Department of Biostatistics and Epidemiology, School of Health, Scientific Research Center, Tehran University of Medical Sciences, Tehran, Iran
