Implementation of the corporate social responsibility (CSR) concept is presented, as it applies to the practice of companies. The authors focus on an isolated area of CSR implementation, namely the improvement of working conditions, in the context of selected international standards and norms directly referencing the CSR concept. Circumstances of practical implementations in this area are presented, based on results of pilot empirical studies. The context of the implementations is analysed, as well as their correlations with the task of practical realization of the CSR concept.
