With a growing body of literature linking systems of high-performance work practices to organizational performance outcomes, recent research has pushed for examinations of the underlying mechanisms that enable this connection. In this study, based on a large sample of Welsh public-sector employees, we explored the role of several individual-level attitudinal factors--job satisfaction, organizational commitment, and psychological empowerment--as well as organizational citizenship behaviors that have the potential to provide insights into how human resource systems influence the performance of organizational units. The results support a unit-level path model, such that department-level, high-performance work system utilization is associated with enhanced levels of job satisfaction, organizational commitment, and psychological empowerment. In turn, these attitudinal variables were found to be positively linked to enhanced organizational citizenship behaviors, which are further related to a second-order construct measuring departmental performance.

This paper reports the findings of a study conducted on UK local government workers in which the effects of social and negative exchanges on work-related attitudes and behaviours were assessed. HR practices and organizational climate were used as measures of social exchange. Negative exchanges were based on measures capturing nonsupportive management practice and unfair treatment. The findings suggest that, consistent with social exchange theory, positive exchanges lead to enhanced worker attitude and behaviour, with negative exchanges leading to increased work-related stress, reduced motivation and a greater propensity to quit. Negative exchanges, however, did not result in reduced discretionary behaviour. Disaggregating the exchange practices revealed equitable rewards and organizational morale had consistent effects on worker attitudes and behaviours, with team working, employee involvement and trust in managers having significant effects on employee motivation. The implications of these findings are considered in the concluding section of the paper.
