Denbighshire social worker Kirsty Ann Morton struck off
A social worker has been struck off after disclosing confidential information about vulnerable children.
A fitness to practice hearing in Flintshire was told Kirsty Ann Morton's actions had "serious and far-reaching implications", making removal from the register the only option.
These included the threat of legal action.
Ms Morton worked for Denbighshire council when it happened in October 2014, the Care Council for Wales said.
She had allowed information about four families, including some involved in child protection cases, to be seen by another person, the hearing was told.
Chairman of the committee Islwyn Jones said Ms Morton had "deliberately" disclosed the information to someone "close to her" whom she felt she could trust.
"Once the information was released the registrant had no control of it," he added.
Mr Jones said the "level of shock, distress and anxiety" caused to the families involved could not be underestimated.
Ms Morton did not attend the hearing and Denbighshire council has been asked to comment.
