Quantitative and Qualitative Job Insecurity and Idea Generation: The Mediating Role of Psychological Contract Breach

This study investigates how quantitative and qualitative job insecurity relate to idea generation, a dimension of innovative work behaviour. We hypothesise that both types of job insecurity relate negatively to this type of innovative behaviour, and expect a stronger association between quantitative job insecurity and idea generation. Moreover, we argue that psychological contract breach mediates (‘explains’) these negative relationships. The hypotheses were tested in a sample of 1420 supervisors from a large Belgian organisation, using hierarchical regression analyses, bootstrapping analyses, and relative weight analysis. The results showed that both types of job insecurity are negatively associated with idea generation. Contrary to our expectations, the relationship between both forms of job insecurity and idea generation was equally strong. Psychological contract breach was found to mediate these relationships.
