This study attempts to examine the relationship among ethical climate, job satisfaction, organizational commitment, and turnover intention in the context of the Malaysian external auditor's work environment. The questionnaire is sent to a sample of external auditors from Malaysian Big Four (Klynveld Peat Marwick Goerdeler (KPMG), Ernst and Young, Deloitte KassimChan, and PricewaterhouseCoopers (PwC)) main offices. There are 167 useable responses. The regression results have provided evidence that ethical climate is directly, significantly, and positively associated with job satisfaction. In contrast, ethical climate appeared not to be directly related with external auditor's turnover intention. Both job satisfaction and organizational commitment were identified as significant predictors in explaining turnover intention, since they had a significant and negative effect on external auditor's turnover intention. This study also implied that job satisfaction had a significant effect on organizational commitment. Furthermore, the findings revealed that organizational commitment partially mediated the relationship between job satisfaction and turnover intention. The results extend the literature on external auditor's turnover intention and provide insights for human resource management in accurately assessing employee's turnover intention in order to improve retention and reduce actual turnover particularly in audit firms. 展开更多
