UPDATE 9.45am: A FACS spokesman has responded to concerns by workers and the new IT system called ChildStory.

"The launch of ChildStory has changed the way many FACS staff work, and has involved data migration of over 20 years' of information from a legacy system," he said.

"FACS appreciates that the change has caused frustration as staff transition to a new system.

"To ensure staff are able to easily use ChildStory in the course of their work, FACS is working to provide more support and is continuing to make improvements to the system.

"FACS is listening to staff feedback and continually improving training and workshops, and providing additional on-site support in FACS offices.

"FACS has also increased the number of Helpline staff, invested heavily in training and brought in additional specialist resources to ensure the system operates effectively and efficiently.

"ChildStory is putting children and young people in care at the centre of their story with a network of family, carers and caseworkers."

INITIAL  5am: UP TO 30 Family and Community Services workers will walk off the job at Lismore tomorrow in protest to a new system that the public service union argues puts vulnerable kids at risk.

At 12.30pm, Lismore staff and Public Service Association members will gather at the department's Zadoc St office in Lismore to oppose the ChildStory system.

ChildStory is an IT system that was implemented in November last year that manages a supported child's family, carers, caseworkers and other service providers around them.

Association organiser Asren Pugh said the system "is just not working" and prohibiting FACS workers from doing their jobs and protecting children.

Mr Pugh said since transferring to the new system, important data about in-care children has been lost and workers are unable to process payments to carers for services such as doctors check ups and school fees.

"They can't provide proper care for the children," he said.

Protesters will call on Family and Community Services Minister Pru Goward, to halt the rollout of phase two of the controversial system.
