An estimated 28 million people are employed in forced labour in supply chains. Procurement professionals are on the frontline of this global crime - one estimated to be worth half a trillion dollars. It is a challenge the CIPS Foundation is working with UK-based modern slavery charity Unseen to tackle head on by providing funding to turn data from its Modern Slavery & Exploitation Helpline into actionable insights for procurement professionals.  In this CIPS Foundation special we lift the lid on an issue that exposes organisations to significant financial, legal and reputational risks - where "plausible deniability" is no longer an option and fundamental human rights are at stake. Andrew Wallis OBE, CEO of Unseen, and Sodexo's Madeline Fitton MCIPS, founder and chair of the BSA Modern Slavery Council, share what progress has been made 10 years on from the UK's landmark Modern Slavery Act. We uncover the scale of the challenge facing procurement, address why effective legislation must be designed as a "spiky carrot", and provide essential advice on how to identify and respond to modern slavery in your own supply chain.
