Servant and authentic leadership as drivers of innovative work behaviour: the moderating role of creative self-efficacy

Abstract

Purpose: The importance of innovation has attracted growing attention due to the complex and rapidly changing business environment. This study aimed, first, to examine the joint effect of servant and authentic leadership (AUL) styles on employee creativity (EC), second, to examine the direct and mediated effect of servant leadership (SL) on employees' innovative work behaviour (IWB), third, to examine the effect of EC on IWB and finally, to investigate the moderating effect of creative self-efficacy (CSE) on the relationship between AUL and EC. Design/methodology/approach: A quantitative approach was used, and the data were collected from 446 employees in the Qatari public sector. The data were then analysed by employing partial least squares structural equation modelling (PLS-SEM) using SmartPLS software to validate the measures before testing the proposed model. Findings: The results of this study emphasized the strong hypothesized link between EC and IWB. It also endorsed the mediating role of EC between SL and IWB and the moderating role of CSE in the AUL-EC relationship. Originality/value: The originality of this study comes from various aspects. First, it is unique in separately examining EC and innovation and the link between them. Second, it investigates the joint impact of servant and AUL styles on EC. Third, it explores the mediating role of EC between SL and IWB. Fourth, the moderating effect of CSE on the AUL-EC link also was examined to gain a full understanding of the relation effect. Finally, the value of the current study also comes from the integration of the triangular theory of creativity, SL and AUL theories and self-efficacy theory to explain the proposed model of the study. Moreover, this study serves as a guideline for decision-makers on how to enhance IWB among employees by focusing on leadership programmes and the creative and innovative culture.
