We have posted before on the newly-enacted UK Modern Slavery Act 2015 (see here and here). We were honored recently to be interviewed by Compliance Week concerning compliance with this new law. As the article notes, we are all still awaiting further guidance, anticipated this month, regarding what companies need to do to comply.
One point that we made in the article, is that if you enact a supplier policy concerning slavery and human trafficking, in response to this new law or otherwise, your policy is only as good as its implementation. Be sure your supplier contracts allow you to get the information from suppliers that you need, and that suppliers are required to certify compliance, or to allow you to audit their practices. When in doubt, a compliance review can verify where you stand with your supply chain.
