INTRODUCTION: VOLUNTEERS ARE A SET OF CRUCIAL HUMAN RESOURCES IN MANY GOOD SPORT ORGANIZATIONS. UTILIZING VOLUNTEERS WHICH PLAYS A PIVOTAL ROLE IN THE PROCESS OF HUMAN RESOURCE MANAGEMENT IS ALSO OF GREAT IMPORTANCE IN PROSPERING NEARLY IN ALL SPORT EVENTS. BESIDES, WORK ETHIC CAN BE CONSIDERED AS A KEY FACTOR IN GOOD PERFORMANCE IN A COMPETITIVE ENVIRONMENT. STUDIES SHOW THAT INDIVIDUALS WITH HIGH WORK ETHICS ARE LIKELY TO FEEL RESPONSIBILITY TOWARD THE UPS AND DOWNS OF THEIR ORGANIZATIONS AND CAN HELP IN URGENT OCCASIONS, AS WELL AS DOING THEIR OWN JOB DUTIES. THUS, TAKING WORK ETHICS INTO ACCOUNT IN ORGANIZATIONS IS HIGHLY SIGNIFICANT. THE AIM OF THIS STUDY IS TO FIND AN ANSWER TO THE QUESTION "IS THERE ANY SUGGESTIVE DIFFERENCE IN THE PRIORITY OF VOLUNTEERS’ WORK ETHICS? " METHODOLOGY: THE METHOD APPLIED IN THIS RESEARCH WAS DESCRIPTIVE. THE SAMPLE IN THIS STUDY CONSISTED OF 140 VOLUNTEERS AT THE 12TH UNIVERSISTIES SPORT OLYMPIAD WHICH WAS HELD IN SHAHID BEHESHTI UNIVERSITY IN YEAR 1393.133 OF VOLUNTEERS COMPLETED THE QUESTIONNAIRE. FOR COLLECTING DATA DEMOGRAPHICS AND WORK ETHIC PETTY QUESTIONNAIRES WERE USED (1990). FRIEDMAN TEST WAS USED TO PRIORITIZE DIMENSION WORK ETHIC (A<0.001).RESULT: THE 133 VOLUNTEERS IN THE STUDY, %45.1 FEMALE, %54.9 MALE, %18.8 OF THEM WERE MARRIED AND %81.2 OF VOLUNTEERS WERE SINGLE. THE RESULTS SHOWED, THERE IS A SIGNIFICANT DIFFERENCE BETWEEN THE PRIORITY OF VOLUNTEERS DIMENSION WORK ETHIC.DISCUSSION: IN THIS STUDY VOLUNTEERS INTRODUCED CLEAN AND HUMANLY RELATIONS AT WORK AS THE MOST IMPORTANT WORK ETHIC, WHICH WAS QUITE ANTITHETICAL TO THE RESULT OF ZOLFAGHARI AND MOHEBBI’S RESEARCH (1393). IT IS THINKABLE THAT THE MATTER OF SHORTNESS OF TIME IN VOLUNTEERS’ ACTIVITIES HAS LED THE VOLUNTEERS TO CONSIDER ESTABLISHING ETHICAL RELATIONS AS THE PRIMER ISSUE TO ENABLE THEM TO DISTANCE THEMSELVES FROM THE TENSIONS IN THEIR LIVES. INTEREST IN WORK WAS INTRODUCED AS THE SECOND FACTOR IN WORK ETHIC, WHICH TURNED OUT TO BE ANTITHETICAL TO MOEEDFAR’S RESEARCH. IT IS ALSO POSSIBLE THAT SUCH INCONSISTENCIES COULD RESULT FROM DIFFERENCES IN STATISTICAL SOCIETY AND MISMATCH BETWEEN JOB SKILLS AND JOB DUTIES THAT VOLUNTEERS ARE SUPPOSED TO DO. THEN SERIOUSNESS AND PERSISTENCE WERE CHOSEN AS THE THIRD PRIORITY, WHICH WAS IN CONTRAST WITH ZOLFAGHARI AND MOHEBBI’S RESEARCH RESULT. IN ORDER TO IMPROVE THIS THIRD PRIORITY, SPORT DIRECTORS CAN OFFER GOOD SERVICE TO ENCOURAGE VOLUNTEERS TO DO THEIR DUTIES WITH MORE DETERMINATION. COOPERATION WAS INTRODUCED AS THE LEAST IMPORTANT FACTOR, AND THIS RESULT WAS TURNED OUT TO BE RATHER AGAINST THOSE OF MOHEBBI (1393) AND MOEEDFAR’S RESEARCH RESULT (1395). IT IS PROBABLE THAT IN THIS SPORT OLAMPYAD TOURNOMENT, THE HIGH VOLUME OF WORK ASSIGNED, AND INADEQUATE DISTRIBUTION OF VOLUNTEEERS IN VARIOUS POSITIONS LED THE VOLUNTEERS TO GIVE THE LEAST IMPORTANCE ON THE LEAST FACTOR MENTIONED.
