Although there are several conceptions of organizational moral learning (OML), there is a need for more empirical studies. This study aims to provide illustrations of the dynamism of organizational moral learning by spiritual hearts (OML-SH), where OML and organizational immoral learning (OIL) are coupled antagonistically. Two OML-SH initiatives (i.e., the Quality Control Circle program and 100-hour training record system) within Brunei’s public sector are scrutinized to illustrate the dynamic process of OML-SH, spanning individual, group, and organizational levels. From the two (...) exploratory case studies, the purifying mechanism was coined to capture the laminated interplay between the spiritual hearts, group understanding, leadership, organizational intention, structure, culture, and resources to drive OML. In contrast, the corrupting mechanism was also coined as the opposite force to drive toward OIL. From the study, leadership and organizational learning repositories were seen to play essential roles in the purification of the spiritual heart (i.e., individual moral development). Additionally, the spiritually diseased hearts occupying the two extremes of OML and OIL were seen to experience moral ambivalence, which was also not captured in previous studies. The paper concludes with suggestions to manage moral ambivalence for more positive outcomes, drive OML further and impede OIL simultaneously. (shrink)
