In an organisation, the branch head circulates a new RBI

Solution

Downward communication flows from higher levels of the organisational hierarchy to lower levels from superiors to subordinates. Circulating an RBI circular from the branch head to team leaders and officers is a classic instance of downward communication: directives, policies, circulars, and instructions flowing top-to-bottom. Upward communication flows from subordinates to superiors (e.g., feedback, grievances). Horizontal is peer-to-peer. Diagonal cuts across departments and levels. Grapevine is informal and unofficial.
