More exploration and examination about the circumstances that force individuals to behave unethically in an organisation is needed, as an unethical culture in an organisation discourages organisational innovation. Therefore, the present study aims to examine the relationship between employee expediency and workplace ostracism, which will allow the researchers to gain more insight into it practical implications. The research will draw upon the affective event theory (AET) to examine the hypothesised relationship between workplace ostracism and employee expediency, using the mediating effect of emotional exhaustion and the moderating role of moral identity. In order to test these hypotheses, 272 responses were analysed via PROCESS macro Findings show that when employees face ostracism at their workplace, the feeling of social rejection develops into a situation in which they show affective response, which may trigger employee expediency even in the presence of moral identity. Hence, this study proves that workplace ostracism develops such feelings in employees, which makes them indulge in unethical behaviour.
