Perceived organizational support and knowledge sharing: employees’ self-construal matters

HR professionals are expected to become more involved in knowledge management and facilitate knowledge sharing among employees in the knowledge economy. In this study, we investigated the relationship between perceived organizational support and knowledge sharing by taking account of employees' interdependent and independent self-construal. Our hypotheses were examined using a 2-wave survey data-set from 145 teachers working at 4 Dutch vocational education and training schools. The results showed that perceived organizational support was positively related to knowledge sharing for employees either with a high interdependent self or with a low independent self. However, this positive relationship disappeared for employees either with a low interdependent self or with a high independent self. Overall, the moderating effect of self-construal revealed a new avenue towards a better understanding of the relationship between organizational support and employees' knowledge sharing. It provided a tentative answer to the question of why organizational support does not often succeed in motivating employees to share their knowledge in the workplace.
