PurposeCombating and detecting fraud is a daunting task, especially in the Nigerian banking sector, because it necessitates a thorough understanding of the nature of fraud, as well as how it can be performed and concealed by fraudsters. Therefore, the purpose of this study is to empirically examine the relationship and the predictive ability between amoral behavior, control climate and perceived job insecurity on fraudulent intentions among bank employees in Lagos Metropolis.Design/methodology/approachDescriptive and cross-sectional designs were used to select employees from 12 banks using predetermined scales. In total, 1,080 questionnaires were distributed, but 950 were retrieved and analyzed. The study used multistage sampling by applying cluster, purposive and simple random sampling techniques. Correlation and hierarchical regression analyses were used to analyze the data.FindingsA significant positive relationship and predictive abilities were established between employee’s amoral behavior and fraudulent intentions on the one hand, and employee’s job insecurity and fraudulent intention on the other, going by the additional variance identified when each variable was added in each step, implying that employees who exhibit amoral behavior are likely to engage in fraudulent intentions. In the same manner, employees who feel insecure are likely to engage in fraudulent acts because they would want to secure their future. However, there was a significant negative relationship and predictive ability between control climate and fraudulent intention; implying that inculcating a strict control climate minimizes or totally eradicates employees’ intentions to commit fraud.Research limitations/implicationsThis paper is limited to amoral behavior, control climate, perceived job insecurity and fraudulent intentions; it is limited to employees in the banking sector, with a special focus on emerging economies, Nigeria, West Africa. The implication of this is that the result may not be generalized to other sectors and other countries.Practical implicationsThe practical implication of the study is that managers should be aware that employees who are in danger of losing their jobs are more likely to engage in the fraudulent act, and this should be looked into. Training and retraining, workshops, conferences and seminars on employee morale behaviors as well as strict adherence to ethical codes of conduct are vital to enlighten the employees on the dangers of perpetrating fraud and the impact on themselves and the economy at large. Control climate is a very vital tool in curtailing the incidences of fraud in the organization.Originality/valueThis paper contributes to the knowledge by filling the gaps left by a lack of empirical examination into the combined influence of amoral behavior, control climate and perceived job insecurity on fraudulent intentions, especially among bankers in Lagos Metropolis. It provides management with guides on how to drastically reduce the menace of fraudulent intentions in the banking sector and by extension in other non-banking organizations.
