Current literatures show that study on work ethics is gaining popularity among researchers for a very obvious reason, namely the threat of moral hazards. Cases of corporate scandals and collapses provide evidence that moral misconducts among employees have contributed to the financial disaster of many companies. It is believed that there is a possible relationship between work ethics and organizational commitment, thus performance. This study would therefore attempt to investigate the Islamic Work Ethics (IWE) practices among the employees of banking institutions in Malaysia with specific focus given to the possible relationship between IWE variables and organizational commitment (OC). The findings of this study indicate that all IWE variables are positively and significantly related to organizational commitment.
