In this study we investigate the antecedents and outcomes of employees' trust in their supervisors and organizations in Chinese joint ventures. We develop a model that links trust, job security, and subordinate-supervisor guanxi. The model considers job security as an antecedent of trust in the organization and subordinate-supervisor guanxi as an antecedent of trust in supervisors. It further suggests that the turnover intention of employees is affected by their trust in their organization, and that their organizational citizenship behavior is affected by their trust in their supervisors. We use a data set consisting of 295 employees collected in four joint ventures in Southern China to test the hypotheses. The results of our LISREL and OLS regression analyses support the proposed model. Job security and subordinate-supervisor guanxi are found to affect employees' trust. In addition, trust in the organization has a stronger effect on turnover intention than does trust in one's supervisor. Trust in supervisors significantly affects the organizational citizenship behavior of employees. These findings have practical implications for the management of workers in Chinese joint ventures. © 2003 Kluwer Academic Publishers.
