Informal communication is a type of casual and not formal communication that can take place between two or a group of individuals in the workplace or outside the workplace. The exchange of information is typically unplanned and impromptu. These types of conversations or discussions are not aligned to the official rules of communications of an organization. Anyone can be part of an informal communication and often enough it’s difficult to define the start and end of the conversation.
Informal communication in the workplace is often called ‘grapevine’ and often begins by employees with social relations. In many cases, informal communications can turn to formal communication if they are added in the formal communication information flow of a company.
