The performance of employees is increasingly seen as an important contribution to the overall firm success. The relevance of human resource management as a strategic tool is thus also increasing. Besides the positive impact on individual productivity it can help to retain employees in the long-run. The aim of this project is to analyze the impact of human resource management measures on the employment stability within firms. Examples for these measures are profit-sharing or support for work-life balance. Because they are generally combined our focus is on bundles of human resource measures. Moreover, we will analyze the heterogeneous impact on different groups of employees which differ for instance with regard to education or age. The linked employer-employee data from the Institute for Employment Research (IAB) serves as an appropriate database for this purpose.
