The article deals with the influence of organizational ethics program components on managerial ethical behavior. The main aim was to establish which EP components are perceived as valuable and useful to foster the ethical behavior of managers. Moreover, we also aimed to investigate the role of ethics training in this context and to explore whether it can potentially increase managers’ trust in EP components as effective tools for the promotion of ethical behavior. The article advances the EP theory in several (...) ways. It offers novel insights into both business ethics and EP development in the specific cultural and social circumstances of a former socialist country in the Central and Eastern European region, Slovakia. It shows that codes of ethics and related reporting and control mechanisms are perceived as the most effective EP components to shape managerial ethical behavior. Furthermore, based on empirical evidence, and to some extent contrary to prior theory, the article unveils three EP functions, namely the ‘compliance with group norms,’ the ‘ethics education through collective discussion,’ and the ‘counselling and resolving of ethical issues’ at workplace. In addition, the article shows that ethics trainings can help to boost the trust of managers toward EP components and might be conceptualized as a precursor for an effectively functioning EP. (shrink)
