In this study, it was intended to identify the effects of abusive supervision and social support on counterproductive work behavior and task performance of cabin crews working in the two Full Service Carriers(FSC). To meet the specific objectives of the study, a survey was carried out by the means of self-administered questionnaire to a sample of 226 cabin crews before cain briefings. Out of 226 returns, a purposive sample of 216 valid questionnaires formed the basis of this study. The data was analysing SPSS to provide descriptive, reliability and validity tests, multiple regression and simple regression. First, the analysis results showed that abusive supervision has a significant impact on counterproductive work behavior. Second, it has been found that abusive supervision and social support have a significant impact on task performance of cabin crews. Third, counterproductive work behavior like a deviant task showed a significant impact on task performance of cabin crews. Through this result, it provides further suggestions for clarifying counterproductive work behavior that can lead to the task performance in airline service, and improving social support of airline crews and use as basic data for effecive task performance in FSC.
