The questionnaire is deployed on a risk basis, according to the nature of services provided.

    Suppliers are required to report what steps they are taking regarding identifying the risk of modern slavery within their particular supply chain which will allow Mercer to better assess the potential risks of modern slavery in its own supply chain.
