Purpose Job characteristics can potentially influence employees’ attitudes and behaviors. However, their impact on employees’ innovative behaviors, particularly in public sector organizations, has received little scholarly attention. Based on relational job design theory and the broaden-and-build theory of positive emotions, this study aims to examine the effect of job contact on public sector employees’ innovative work behavior through the mediator of happiness at work. It also assesses whether prosocial motivation strengthens the influence of job contact on innovative work behavior (via happiness at work). Design/methodology/approach The model was examined on a sample of 180 employee-supervisor dyads (90 supervisors and 180 employees) recruited from various government departments in the United Arab Emirates. Findings The findings support the proposed moderated mediation model in which job contact positively and significantly impacts innovative work behavior. The association between job contact and innovative behavior via happiness at work is found to be stronger for employees who are highly prosocially motivated. Originality/value The findings offer prescriptive insights into public sector employee happiness and prosocial motivation by illustrating when and how job contact influences innovative work behavior. The authors also present relevant managerial recommendations for promoting public sector employees’ innovative behavior.
