The social responsibility of a business includes the obligations to make a profit, comply with the law, be moral and be a good citizen. In this respect, businesses need to develop strategies that combine financial profitability with environmental and social benefits in order to harmonize social, ethical and ecological concerns with economic issues. Accordingly, social and environmental performance is as important as economic performance for businesses. Especially since the 1990s, the economic, environmental and social responsibilities of businesses have started to attract attention with the concept of “sustainability”. Businesses are also expected to implement sustainability practices by creating their own values, principles and goals by following the basic principles and goals of sustainability. While the direct effect of sustainability in businesses can be observed in economic and environmental dimensions, its indirect effect can emerge in social dimensions due to reasons such as gradual changes and the spread of cultural results over the long term. Accordingly, it is recommended that businesses focus on social sustainability activities with a visionary approach with patient, realistic expectations in order to make long-term, permanent and constructive contributions to social life. In the light of these explanations, this section first includes explanations regarding the concept of corporate social responsibility, then moves on to the concept of social sustainability and explains social sustainability in businesses within the scope of indicators, performance, culture and strategies.
