The management of a growing number of organizations recognizes their responsibility for a positive impact on society and the environment, so by actively including social responsibility in the strategy, they improve their reputation, attract talent and encourage innovation, which ultimately leads to sustainable growth and competitiveness of the company. Considering the increasingly pronounced awareness of responsibility towards society and the environment, socially responsible business is becoming extremely important in the world of business. The traditional focus on the exclusive maximization of profits is gradually being transformed into an approach that strives for optimal business, while simultaneously taking into account economic, social, environmental and managerial dimensions. This paper investigates the implementation of socially responsible business in hotel companies with special emphasis on two leading hotel companies in the Republic of Croatia. The research is aimed at understanding the importance and benefits of socially responsible business in the context of the hotel industry. The hotel industry has not always been in the spotlight when it comes to this topic, but today it is increasingly recognizing its importance for sustainability and long-term success. A case study analyzing the impact of CSR on hotel chains showed how the observed companies deal with different aspects of social responsibility.
