This paper examines the scope, types, and degree of corporate social responsibility (CSR) practices currently employed in human resource management (HRM) in Spain, and its determinants. It analyses firm, employee, and job‐related characteristics which affect the implementation of CSR in HRM. It also offers an overview of the current situation regarding CSR in HRM for a wide range of economic sectors, employees, job characteristics, and HRM practices. Information is obtained from employees rather than CEOs. Results show that companies do not engage in CSR practices to the same extent. The scope of CSR differs among types of HRM practices. The practices curently applied are grouped more according to type than to degree of responsibility. Another relevant result is that some variables such as a firm's dimension, have a clear effect on the likelihood that an employee benefits from responsible labour practices, but their effects generally vary for different types of practices.
