Policies include: Whistleblowing policy, Employee Code of Conduct, Supplier/Procurement Code of Conduct, Recruitment / Agency Workers Policy.
While their due diligence mechanisms focus on new suppliers they mention 2 measures that apply to general enforcement of their anti-human trafficking and anti-slavery policies:
"- Creating an annual risk profile for each supplier."
"- Invoking sanctions against suppliers that fail to improve their performance in line with an action plan or seriously violate our supplier code of conduct, including the termination of the business relationship."
Should this value not be just "Tier 1"? It doesn't explicitly specify that the policies apply beyond Tier 1.
I have updated this value to "Tier 1" based on the discussion above.
