An open letter to Coles and Woolworths about modern slavery risks initiated by Martijn Boersma, Justine Nolan, and Laurie Berg of the University of Technology Sydney and the University of New South Wales has called the supermarkets to:

• "take a multi-stakeholder approach to supplier certification that actively involves workers and their trade unions
• actively involve trade unions in labour rights education and in grievance procedures.
• ensure that all contracts with suppliers are sufficient to deliver at award wages to all workers."

Business & Human Rights Resource Centre invited Coles and Woolworths to respond to the open letter. The companies' responses are linked below.
