Scottish social work leaders have warned that proposals to prosecute failing social workers would make them more risk averse in their practice.

The proposals, part of a wholesale children's services reform outlined last week by the Scottish executive, could see social workers sent to prison if they are deemed to have failed a child in need.

Duncan MacAulay, general manager at Edinburgh Council's health and social care department, said he was concerned the move would undermine professionals' confidence and put others off coming into the field.

He said: "I support accountability but the threat of the sword over people's heads could drive them away from the profession."

Maggie Mellon, director of children and families at charity Children 1st, said the proposal was "crazy" and that the fear of making mistakes would affect professionals' ability to work together and be creative.

Tom Wood, chair of the Edinburgh drug action team, called the proposals "unhelpful". He added: "Professionals are more than aware of their responsibilities. Threats will force them to take a more mechanistic approach to decision-making."
