In the Verification paragraph of Macy's Modern Slavery Act statement it states "Macy’s and Bloomingdale’s supply and legal executives meet on an annual basis, and informally as needed, to assess the risk of human trafficking and slavery in our supply chains and to assess whether our policies and procedures appropriately address those risks."
but it does not explain how the company asses the risk of human trafficking in their supply chain. it just states that supply and legal executives meet up to discuss the risk of human trafficking and slavery in the supply chain
It can be considered as under desk research as company executives are doing risk assessment.
