PurposeAlthough existing studies demonstrate positive relationships between ethical cultures and innovativeness, their explanations of why an ethical culture leads to innovativeness are limited. This study explores the relationship between ethical organizational culture and knowledge workers' innovativenessDesign/methodology/approachBased on Kierkegaardian existential philosophy, this study proposes a research model that employs knowledge workers' existential affirmation as the link between ethical culture and innovativeness. The main hypothesis proposed in this study is that ethical organizational culture offers knowledge workers the opportunity to find their existential affirmation, which leads them to become more innovative. A structural equation modeling analysis is based on data collected from a survey of 348 knowledge workers from small and medium-sized enterprises (SMEs) in different hi-tech industries.FindingsThe findings suggest that among the four subdimensions of an ethical organizational culture, ethics training and awareness raising had the strongest relationships with knowledge workers' existential affirmation, which, in turn, had a significant relationship with their innovativeness.Originality/valueBased on this philosophical reflection, this study develops a research model that examines knowledge workers' existential affirmation as the factor that links ethical organizational culture and knowledge workers' innovativeness. The authors test ethical organizational culture as an environment that allows knowledge workers to validate their existential affirmation. Further, they test the link between knowledge workers' existential affirmation and their innovativeness.
