RT Article T1 Top-down knowledge hiding in organizations: an empirical study of the consequences of supervisor knowledge hiding among local and foreign workers in the Middle East JF Journal of business ethics VO 164 IS 3 SP 611 OP 625 A1 Arain, Ghulam Ali A1 Bhatti, Zeeshan Ahmed A1 Ashraf, Naeem A1 Fang, Yu-Hui LA English PB Springer YR 2020 UL https://ixtheo.de/Record/1700561774 AB This study adds to the growing research exploring the consequences of knowledge hiding in organizations. Drawing from the social exchange theory and the norm of reciprocity, this paper examines the direct and indirect—via distrust in supervisor—relationships between supervisor knowledge hiding (SKH) and supervisee organizational citizenship behavior directed at the supervisor (OCB-S) in the context of the Middle East. Using a supervisor–supervisee dyadic design, two-source data were obtained from 317 employees (local and foreign) of 41 Saudi firms. The findings suggest that supervisees’ distrust in their supervisors mediates the significant and negative relationship between SKH and supervisees’ OCB-S. Furthermore, the significant and positive relationship between SKH and distrust in supervisor is more pronounced for foreign workers than for local workers. This study provides empirical support and a better understanding of the existence and consequences of SKH for local and foreign workers and also discusses the theoretical and practical implications of the findings.
