Abstract
Social workers may be asked to practise in ways which they consider to be unlawful or contrary to best practice as defined through reference to values and knowledge. How might they respond? This article explores how far legal knowledge can support practitioners who are concerned about systems operated by, and decisions taken by their employing authorities. Can the law assist those practitioners who are committed to seeking to challenge and change how agencies function? The article seeks to connect the law to the dilemmas encountered by social workers as employees and as professional practitioners. The analysis concludes with consideration of the introduction of the General Social Care Council.
