Ethics plays an essential role for the success of all business units. These days, it is not sufficient to boost the performance of supply chain companies just by focusing on financial figures but we need to consider the ethical dimensions, particularly at an organizational level. It is evident from the prior investigations that the performance of the supply chain industry in most of the Arab countries has not gained reasonable growth. Most of the Arab countries are facing issues for development good supply chain management in various departments. Bahrain maintains a low performance in the supply chain compared with other Arab countries such as Oman, Qatar, Kuwait, United Arab Emirates (UAE) and Saudi Arabia. The logistics index of Bahrain has been decreasing in recent years. Therefore, to address this problem, the objective of this study is to examine the role of workplace ethics in supply chain management among supply chain companies of Bahrain. The study considers three dimensions of ethics, namely; organization culture ethics, leadership ethics, and training ethics. Employees on the managerial positions are selected as the respondents. These respondents are selected from the supply chain companies of Bahrain. Questionnaires are distributed among these employees to collect the data. By using the structural equation modeling, data are analyzed through PLS. The results conclude that workplace ethics has significant contribution in supply chain management. Better implementation of workplace ethics always contributes positively on supply chain management.
