A recent investigation by the BBC has revealed that major corporations, including McDonald's and large supermarket chains, overlooked signs of modern slavery within their operations. The report highlights that victims were found working in a restaurant and at a supplier for a supermarket, yet the warning signs went unnoticed. This raises serious concerns about the effectiveness of monitoring and safeguarding practices in these prominent businesses. The findings underscore the urgent need for improved vigilance and accountability to combat human trafficking and exploitation in the supply chain.
