It is important to maintain confidentiality because a breach of confidentiality can be very upsetting. It can weaken the trust between a professional and a client. If there has been a breach of confidentiality it is important to determine if and why a disclosure was made. Firstly you should obtain a copy of the guidelines on confidentiality used by the organisation. You may wish to ask the person who breached your confidentiality under what grounds they did this. An advocate should be able to help you do this.
