The main aim of this thesis is to identify the form of social responsibility in individual companies. Every business on the slovak market processes and monitors data that contribute to improvement, either in its corporate or social environment, but not every business has enough financial or human resources to properly sort and implement this information. The first chapter focuses on the characteristics of corporate social responsibility. We introduce the concept of social responsibility, basic principles, benefits, respectively. advantages and disadvantages and, last but not least, reporting as a tool of socially responsible business. The aim and methodology of the work are presented in the second and third chapter, in which we specify our analysis and what means we used to obtain it. The fourth chapter is the subject of social responsibility in individual companies in Slovakia. Through the Sustainable Development Report or the Corporate Social Responsibility Report, we monitor the priority characteristics of individual businesses. Using a questionnaire, we evaluate what businesses do in Corporate Social Responsibility Reports. The evaluation of the results and the draft recommendations is the fifth chapter in which we will put forward concrete proposals for improving corporate social responsibility in small and medium-sized enterprises.
