This study explores central questions related to the connections between a firm’s High-Performance Work System (HPWS) and its ability to foster the positive employee outcomes, Psychological Capital (PsyCap) and Future Time Perspective (FTP). Drawing on signalling theory, this paper develops and examines two mediation models. In the first, FTP is proposed as mediating the HPWS-PsyCap relationship; and in the second, PsyCap is proposed as mediating the HPWS-FTP link. Self-reported survey data was collected from bank employees in Cyprus, Turkey and the United Arab Emirates (UAE). Results from Partial Least Square Structural Equation Modelling (PLS-SEM) revealed that HPWS exerts a positive influence on FTP and PsyCap. The mediation effects hold for all the countries. Deploying signalling theory enriches our understanding of organisational HRM practices and their possible impact on employees. Implications for practice and research are highlighted.
