The UK’s Modern Slavery Act 2015 added an important new human rights obligation on larger businesses, to make an annual ‘slavery and trafficking statement’. Although the statutory duty for companies to report has not yet kicked in (it will become obligatory for financial years ending on or after 31st March 2016), we have found a surprising number of early reporters.Our analysis of a hundred modern slavery statements provides pointers for companies that are currently putting together reports in terms of what early adopters are saying about their modern slavery risks and processes. Overall, our study shows that, while companies are comfortable to state their policies and describe existing audit processes, they are being tentative in revealing much about non-audit based due diligence processes and also the actual risks of modern slavery that might exist in their own businesses or supply chains...The lack of information on identified risks, either in terms of geographical location, type of product or supply chain, is a significant omission and is likely to result more from companies’ reticence to reveal challenges than the actual level of risks. Although NGOs have stated that they will welcome openness, only a few companies are currently accustomed to ‘warts and all’ reporting. It is to be hoped that confidence to make more detailed disclosures will build...By sector, the highest numbers of companies, just short of a quarter, are in the manufacturing sector, followed by food and agriculture (17%), professional services (15%), IT (10%), construction (9%) and retail (8%). The prevalence of statements among manufacturing, food companies and retailers is perhaps to be expected given their exposure to ethical supply chain issues but the number of reports made by professional services and IT companies is more surprising.
