This paper explores the idea of unlearning in Critical Action Learning (CAL) as applied to the wicked problems of organisations and societies. It draws on data and ideas developed during a research project conducted for "Skills for Care" by Pedler, Abbott, Brook and Burgoyne ("Skills for Care" 2014) and from experiences on development programmes for social workers on action learning facilitation in 2012 and 2013 with Christine Abbott of the Centre for Action Learning Facilitation (C-ALF).
