Final answer:
During a human trafficking compliance review, (C) the collection of employees' personal social media information should not be included. Other necessary activities include the verification of identification documents, inspection of employment records, and interviews with employees and management.
Step-by-step explanation:
Collecting personal social media information of employees is not relevant to compliance reviews focused on human trafficking laws and could violate privacy rights. During such a review, the organization should ensure that employee identification documents are verified, and employment records and payroll documents are in order.
The review should certainly include interviews with both employees and management to gather comprehensive information regarding labor practices. However, when compliance issues are found with a subcontractor, both the subcontractor and the prime contractor must be involved in resolving the issues since prime contractors are generally responsible for ensuring their subcontractors comply with regulations.
