These expectations are specifically outlined in purchase contract terms and conditions, which clearly state our prohibition against any use of child labor or any other form of forced or involuntary labor, abusive treatment of employees, or corrupt business practices in the supplying of goods and services to us. Furthermore, our contracts lay out expectations for lawful compliance with data protection and privacy, wages, hours and conditions of employment, subcontractor selection, discrimination, occupational health/safety and motor vehicle safety. In 2015, we requested that all of our direct suppliers certify compliance with Section 31 of our contract, which specifies lawful compliance for suppliers, and we followed up with those suppliers who did not provide certification.
We require our Tier I suppliers on a global basis to source from Tier II suppliers who meet in-country environment and safety standards, as well as quality standards. However, visibility into supplier relationships, especially at lower levels of the supply chain, is a challenge. We are working to better understand how to manage the risks associated with a multitiered supply chain and continue to collaborate with others in the industry to improve these areas.
An ongoing challenge for us is to advocate for a sustainable and socially responsible supply chain without adding more complexity and burdens to our supplier relationships. This is why we continue to believe that collaboration among auto manufacturers makes sense, particularly given the level of common suppliers among the major automakers. This approach also helps ensure that automotive suppliers are not overburdened by duplicative OEM efforts and have a shared understanding of the key issues up and down the supply chain.
To help guide industry collaboration and individual company efforts, GM and the other OEM members endorse the Automotive Industry Action Group (AIAG) Corporate Responsibility Guidance Statements, which provide guidance on business ethics, global working conditions and environmental responsibility.
Supply Chain Responsibility Training is another way in which we collaborate with AIAG. This training highlights fundamental principles of responsible working conditions and expectations of GM and the other AIAG auto company members, all of which contributed to developing the content of the training. Participants review in detail the areas of child labor, forced labor, freedom of association, harassment and discrimination, health and safety, wages and benefits, working hours, business ethics and environmental responsibility. In 2015, we required all of our employees in Supplier Quality that visit supplier facilities to take AIAG training regarding child labor. AIAG, other AIAG members and GM currently have plans in place to expand this outreach to additional countries in 2016.
In 2014, our efforts focused on updating our training outreach plans around a three-pronged approach – self-assessment, web-based training and in-person workshops using case studies for practitioners. Our goal was to leverage this revamped approach to engage suppliers beyond Tier 1, and we piloted the new program with suppliers in several countries in 2015. AIAG, other AIAG members and GM currently have plans in place to expand this outreach to additional countries in 2016.
