Constructing an index for comparing human resources management sustainability in Europe.

Assuming that a company's institutional context influences its sustainability approach and its human resources management (HRM), this article compares firms' sustainable HRM systems across countries. Despite the presence of a supranational government, different social models exist in Europe according to the level of social protection in each country. The article compares the engagement of companies with sustainable HRM across Europe and develops an index with which to compare HRM sustainability in countries that present significant institutional differences: Germany, Spain, Sweden, and the United Kingdom. The index is constructed based on a formative measurement model, which reflects the implementation levels of sustainable HRM in 106 western European firms. The index reveals significant differences between companies from the four countries and between liberal and coordinated market economies, indicating the need to address the impact of the national institutional context on firms' HRM sustainability.
