A/HRC/30/35 remediation, advocacy on legal and public policy reform, as well as to promote certification and independent investigation. Community- and area-based approaches, which do not target a single crop or commodity, are a key form of a partnership. 69. In relation to businesses, the Special Rapporteur recommends the following: (a) Businesses should adopt human rights policy commitments and conduct continuous human rights due diligence in line with the framework established in the Guiding Principles on Business and Human Rights, and include the findings of the latter in their policies and procedures aimed at eliminating contemporary forms of slavery from supply chains; (b) Human rights policy commitments and supporting policies and procedures should be complemented by effective implementation which moves beyond auditing, and includes third party independent monitoring, proactive investigations, random unannounced assessments that prioritize confidential consultation with workers and strategies linked to prevention of unethical recruitment in supply chains; (c) All businesses’ human rights policies and procedures and the systems to implement them should integrate measures reaching beyond the first tier in supply chains and include clear guidelines and indicators to assist those operating at the lower tiers and in the informal economy to identify human rights violations, including contemporary forms of slavery, and ensure compliance with international human rights standards; (d) Transparency in supply chains is important for ensuring corporate accountability for human rights abuse. Businesses should publicly report on action undertaken to address their human rights impacts, including preventive and corrective measures, and share lessons learned and strategies for improvement; (e) Businesses should provide for or cooperate in remediation by establishing or participating in an operational-level grievance mechanism, in accordance with the Guiding Principles on Business and Human Rights, and cooperate with State-based judicial and non-judicial grievance mechanisms. The approach adopted by businesses in providing for a timely and effective remedy should be community-based and inclusive of, for example, public and/or non-governmental service providers with expertise in working with victims of contemporary forms of slavery; (f) Gaps in national legislation and underdeveloped regulatory infrastructure can pose significant risks for contemporary forms of slavery in supply chains. To address this, businesses, working in partnership with business peers and other stakeholders or though representative industry and employer organizations, should engage public policy actors and regulators to encourage adoption of a relevant legal framework and effective law enforcement. Businesses, together with other stakeholders, also have an important role to play in addressing the root causes of contemporary forms of slavery; (g) Business should engage in capacity-building to ensure management and staff, as well as the relevant business partner, awareness-raising on the nature and risks of contemporary forms of slavery in supply chains and the strategies for its eradication. 70.
