You’re right. A service does have a responsibility to pass on information that is available in the community to support families.
Privacy and confidentiality can be maintained by:
not discussing personal details of an individual to staff who are not involved in dealing directly with that person
always following your organisation's procedures for obtaining written consent to disclose personal information
not disclosing personal details about a co-worker to others without their consent
not providing a co-worker's personal phone number or email to individuals using services
ensuring you have a valid reason for collecting, storing or distributing any personal information
keeping personal information in locked filing cabinets and password-protected electronic files
limiting the amount of written records that are removed from the organisation.
