Diversity of Social Ties and Employee Innovation: The Importance of Informal Learning and Reciprocity

This study examines the relationship between employees' social tie diversity (ties heterogeneity based on organizational functions), innovative work behavior, informal field-based learning, and reciprocity (bidirectional ties proportion). A sample of 182 workers from an Italian clothing manufacturing company was analyzed. The findings reveal that social tie diversity positively influences innovative work behavior, and their relationship is mediated by informal field-based learning. Additionally, reciprocity strengthens the indirect link between social tie diversity and innovative work behavior. This research contributes to the network and innovation literature by corroborating the role of social tie diversity in promoting innovative work behaviors, highlighting the importance of informal field-based learning, and emphasizing the impact of reciprocity. By doing so, this study offers insights into processes and conditions under which social tie diversity has the greatest impact on employee innovation, providing practical implications for fostering innovative work behaviors in organizations.
