Abstract
PurposeThe present paper contributes to the development of sustainable strategies by focusing on the social perspective and the role played by HRM. Specifically, we identified and compared the employee competencies that supported the compliance strategy as well as the innovative/proactive sustainability strategies – and their impacts on social outcomes.Design/methodology/approachAfter formulating hypotheses, we tested them on a sample of 179 companies from the chemical and metallurgical industries using the bootstrap method.FindingsThe results revealed that both sustainability strategies were present in the sample. The compliance sustainable strategy showed to be negatively associated with employee competencies, whilst proactive sustainable strategy firms presented a positive relationship with employee competencies. We also found that compliance strategies failed to have any impact on social outcomes, but proactive strategies had a positive effect on social outcomes. Indeed, normative and foresighted thinking competencies acted as mediating variables in such a relationship.Originality/valueThe originality of this paper lies in three aspects hitherto unaddressed in the literature: first, the conceptualisation and assessment of sustainable strategies focused on a social dimension; second, the identification of individual competencies required developing sustainable strategies; and third, the demonstration that it is only the firms that adopt proactive sustainable strategies that obtain positive social outcomes.
