The effects of a divisionalised and decentralised organisational structure on a formal internal communication function in a South African organisation

Little research exists on the effects of organisational structure on the public relations function. This study focuses on the effects of structural changes on an internal communication function in a large South African organisation. In this organisation internal communication consultants were appointed at divisional level. They had to oversee the election of a communication champion in each cost centre in the division. Survey research conducted 18 months after the process implementation found the structural changes led to improved information flow and face‐to‐face communication. Employees made better use of organisational media and relied less on the grapevine. Although the process made employees less fearful to speak truthfully and improved employee‐supervisor communication, these effects were less pronounced. The research confirmed the important link between public relations strategy and organisational structure, particularly for communication managers and internal communication practitioners in large organisations.
