Informal communication refers to communication that takes place outside of the formal channels or structure of an organization. It is often spontaneous and unplanned, and it typically involves personal and social interactions among employees. Informal communication can take place through verbal or nonverbal means, such as face-to-face conversations, phone calls, text messages, or social media.

Informal communication can be beneficial for building relationships, fostering a sense of community, and promoting a positive work culture. It can also be helpful for sharing information, knowledge, and ideas, as well as for solving problems and making decisions. However, informal communication can also have negative effects, such as spreading rumors, creating confusion, or undermining the formal communication channels.
