How and when overqualification improves innovative work behaviour: the roles of creative self-confidence and psychological safety

Abstract

Purpose

This paper aims to examine the influence of perceived overqualification on innovative behaviour in the workplace. By integrating self-efficacy and human capital theories, this study proposes that perceived overqualification improves innovative behaviour directly and indirectly by boosting employee creative self-confidence. It further investigates the boundary conditions imposed by perceived psychological safety in this process.

Design/methodology/approach

The research utilises a quantitative research methodology through a two-wave survey of 335 employees and their 135 leaders. Moderated and mediated regression analyses were used to analyse the research data.

Findings

The results revealed that perceived overqualification promotes innovative behaviour at work directly and indirectly through its positive influence on creative self-confidence. The mediating effect of creative self-confidence in the relationship between perceived overqualification and innovative behaviour is moderated by perceived psychological safety at work, such that the relationship is stronger in a higher perceived psychological safety condition compared to when it is low.

Research limitations/implications

This study has theoretical and practical implications for personnel management. From a theoretical perspective, it integrates human capital and self-efficacy theories to explain a mechanism through which perceived overqualification will lead to innovative behaviour in the workplace. From a managerial perspective, it mitigates the stigma associated with an overqualified workforce by suggesting that perceived overqualification can be a source of innovation at work.

Originality/value

This is the first study that examines the creative self-confidence-based mechanism in the relationship between perceived overqualification and innovative behaviour at work. It also explores the moderating role of psychological safety in this relationship.
