Human resource management practices and psychological contracts in Swiss firms: an employer perspective

This article investigates the relationship between HRM practices and organisational performance, considering the fulfilment of the psychological contract as an intermediate variable. Apart from testing the influences of a high-investment HRM system index on the psychological contract, the influence of individual HRM practices and their interaction was examined. The sample consisted of HR managers of 92 firms in Switzerland and the data were collected for the Cranfield Network project. The results showed that the high-investment HRM system index predicted the fulfilment of the psychological contract, and some of the individual HRM practices were correlated with the fulfilment of the psychological contract. The interaction effect of performance appraisal and performance-based pay on the fulfilment of the psychological contract showed that performance appraisal is only effective in combination with a tangible consequence in the form of performance-based pay. We neither found a mediation effect for the psychological contract nor an association with organisational performance. This might be due to the fact that the questionnaire was filled in during the financial crisis in 2008 and that the organisational performance was assessed in an economic crisis. Our study sheds light on the relationship between HRM practices and the psychological contract and contributes to the body of research on psychological contracts from a macro level perspective.
