The organization should determine the internal and external communications relevant to the whistleblowing management system, and whenever the policy is launched or revised, staff should be told about its main points and what has changed, with their managers taking part. This gives managers a visible, commonly understood part in the arrangements, and lets staff hear from their own managers that raising concerns about people more senior than them is safe and welcome. A message should also come from top management or the governing body (for instance a personal letter, a newsletter item or an intranet post), lending the initiative weight throughout the organization and showing leadership. The organization should also decide how far other interested parties should be told (the deck quotes the clause).
