Purpose The purpose of this paper is to investigate the relationship between individual work-related curiosity and worker innovation and to test the mediating role of worker divergent thinking. Design/methodology/approach In all, 480 participants, holding 188 different jobs, filled in a validated work-related curiosity scale and indicated their job title. Job requirements in terms of divergent thinking and innovation − derived from the Online Information Network (O*NET) database − were used as proxies for divergent thinking and innovation skills. Findings Results indicated that individual work-related curiosity was a positive predictor of worker innovation and that worker divergent thinking mediated this relationship. Research limitations/implications Individual work-related curiosity supports exploratory skills which support in turn innovation skills. Practical implications Managers could use individual work-related curiosity as a predictor of innovation skills when recruiting, training and guiding employees. Originality/value This study is the first to show an association between individual work-related curiosity and innovation skills across more than 150 different jobs.
