What functions does the informal organization serve?

"The informal organization has several important functions. First, it provides a source of friendships and social contact for organization members. Second, the interpersonal relationships and informal groups help employees feel better-informed about and connected with what is going on in their firm, thus giving them some sense of control over their work environment. Third, the informal organization can provide status and recognition that the formal organization cannot or will not provide employees. Fourth, the network of relationships can aid the socialization of new employees by informally passing along rules, responsibilities, basic objectives, and job expectations. Finally, the organizational grapevine helps employees to be more aware of what is happening in their workplace by transmitting information quickly and conveying it to places that the formal system does not reach."
