The importance of social capital has been recognized in the 1990s and it has been studied more intensively since. Although there is no single definition, it can be said that social capital is a set of norms, rules, behaviors, communications, and networks between members of a community or organization. There are three types of social capital - bonding, bridging and linking social capital, and it is important that there is a balance of these types of social capital in communities. In an organization, social capital can be a crucial factor for the success and survival of an organization. At the organizational level, the structural, relational, and cognitive dimensions of social capital differ. Social capital creates a foundation for collecting and sharing ideas, using shared knowledge, and problem solving. It is also crucial for the success of inter-organizational cooperation, there must be trust, respect and reciprocity between organizations for cooperation to be successful. Microsoft and Google are two multinational companies that have a high level of social capital. Through various benefits for employees, organizations influence the building of trust and loyalty, which contributes to greater motivation and productivity. Informal interactions between employees in leisure and entertainment spaces strengthen the network connections of individuals, but also the organization as a whole, which has the effect of increasing the level of social capital.
