We propose a model that identifies the configurations of relations between environmental practices and other management practices that can improve employee performance, measured as labor productivity. To test our model, we use the qualitative comparative analysis methodology, which allows us to demonstrate empirically how different configurations of management practices, including environmental practices, quality management systems, teamwork, and interorganizational relations, contribute to work systems in ways that increase labor productivity. Our results, based on data from 4,975 employees from 1,866 firms, show (...) that environmental practices are associated with higher labor productivity only when they are combined with other management practices.
