Purpose This study aims to investigate the mediating role of challenging tasks, organizational identification and technological training seeking behavior in the relationship between information sharing as a human resource practice and employees’ feelings of competency at work. Design/methodology/approach Structural equation modeling was used to analyze data collected from a three-wave online survey conducted in an Italian aerospace manufacturing company (n = 294). Findings The results reveal an indirect path between information sharing and feelings of competence, mediated by organizational identification and training seeking behavior. However, no total indirect path was observed between feelings of competency and information sharing through challenging tasks and training seeking. Originality/value This research contributes to the understanding of the impact of information sharing on individuals’ feelings of competency in the context of organizational change, particularly through the introduction of the concept of proactive training seeking as a novel dimension of proactive behavior.
