Internal communication refers to all communication activities implemented within a company or organization for its employees. This process falls under the responsibility of the human resources department and primarily aims to inform, integrate, and engage employees within the organization. Traditional tools used for internal communication include internal correspondence, the intranet, employee handbooks, notice boards, and internal events, among others.

Today, internal communication is increasingly drawing inspiration from marketing and advertising practices, particularly by adopting digital marketing tools and strategies. In addition to internal newsletters, there is a growing use of enterprise social networks to enhance internal communication. Furthermore, video interviews are becoming increasingly common to clearly and visually present the role of the internal communications manager, thus providing a better understanding of this function.

In addition, other resources such as detailed presentations of the profession and its importance, as well as a selection of specialized books on the subject, contribute to enriching knowledge and practices related to internal communication within organizations.
