Discuss the risk and possible solutions with your (indirect) supplier.
Enter into talks with the organisation where the risk occurs. Discuss the risk and see if you can reach a solution together. The CSR Risk Check provides useful tips for goal-oriented actions. Present these tips to the organisation.
If you feel you have to exert more pressure to address the risk, you may want to:
Assess whether the organisation is receptive to promises about future assignments or support in conducting training sessions.
(In case your company represents a large part of the organisation’s turn-over) use this as an argument for change.
Assess whether the organisation’s reputation benefits from cooperation with you, and would be damaged if you would end the relationship.
