It is a known fact that the economic, social and environmental corporate responsibility trends can only be sustainable through the massive involvement of SMEs. This seems even more obvious when faced with the role that these entities play in their economy. Thus, we are interested in how SME managers perceive the concept of CSR and what that translates to in their policies and HR practices. Much research has shed light on the discursive tendencies of CSR and has led us to ask ourselves about the tangible, measurable and engaging nature of so-called socially responsible policies. Therefore, through our exploratory research, we hope to confront reality by choosing a comprehensive qualitative approach based on case studies. Semi-structured interviews, and a two-year period follow -up were carried out among SME managers and allowed the exploration of their various perceptions and associated practices.
