"In turbulent times, corporate entrepreneurship (CE) and high-performance work systems (HPWSs) are expected to expand and flourish. However, research on the influences of both CE and HPWSs on employees' job attitudes has generally been neglected. The aim of this study is twofold. First is to investigate the effects of CE and HPWSs on facets of job satisfaction and the three components of organisational commitment. Second is, consistent with the social exchange theory, to examine whether psychological contract act as an important mediator for the CE, HPWSs and employees' job attitudes relationships. Empirical evidence was obtained from 424 employees in the Greek manufacturing industry. Results indicate that both CE and HPWSs positively impact employees' level of job satisfaction and organisational commitment. In addition, we find evidence that psychological contract theory provides a coherent theoretical framework for understanding these relationships. Theoretical and practical implications for HR managers conclude the article."
