Despite the increasing realization of the significance of work ethics and moral awareness (MA) in businesses after mega scandals, such as those of Enron and Tyco, few studies have investigated the relationship between MA and employees’ performance and the intermediate mechanisms that explain this relationship. This study proposes that as employees’ work ethics are calibrated through ethical training, their MA increases, in turn affecting employees’ job performance. This experimental study is aimed at investigating the impact of MA, increased through ethical training, on employees’ job performance. Based on institutional theory, the multidimensional work ethic profile (MWEP) and strategic human resource management literature, it is hypothesized that MA of employees’ is positively correlated with employees’ performance and that this relationship is moderated by the age, gender and education level of the employees. In particular, the moral awareness component of ethical decision-making (EDM) models is considered as coextensive with work ethics in experimental design, and work ethics is depicted by a multidimensional work ethic profile (MWEP). The study used a sample of 100 employees of a golf club, divided into an experiment group and a control group with 50 employees each. The experiment group was subjected to an ethical training program focused on increasing MA. Employees’ performance for both groups was evaluated based on eight sub-variables. The study concluded that increasing MA increases employees’ performance, with no significant moderation effect of age, gender and education level on this relationship. The results of this study will go a long way in helping managers to increase the productivity of their employees through increased MA.
