Modern slavery is often perceived as a distant issue—something confined to certain regions or industries. In reality, it exists across global supply chains, including those connected to UK businesses.
For organisations today, the challenge is not just awareness. It’s actively identifying, managing, and reducing risk within increasingly complex and multi-layered supply networks.
The Modern Slavery Act in the UK has been law since 2015, many other countries have replicated this including EU legislation. It’s time that you consider it a matter of legal responsibility, ethical practice, and operational risk management.
What is modern slavery in the context of supply chains?
Modern slavery refers to situations where individuals are exploited and cannot refuse or leave due to threats, coercion, or abuse of power.
In supply chains, this can include:
- Forced labour
- Human trafficking
- Debt bondage
- Exploitative working conditions
According to the UK Government’s guidance under the Modern Slavery Act 2015, businesses must take steps to ensure slavery and human trafficking are not taking place in their operations or supply chains.
This makes modern slavery not just a social issue, but a business risk that requires structured oversight.
Why are complex supply chains more vulnerable?
As supply chains expand globally, visibility decreases. A typical supply chain may involve:
- Multiple tiers of suppliers
- Subcontractors across different countries
- Varying labour standards and enforcement levels
The further an organisation moves from its direct suppliers, the harder it becomes to:
- Monitor working conditions
- Verify ethical practices
- Identify hidden risks
This lack of visibility is where modern slavery risks are most likely to exist.
What does UK guidance require from organisations?
Under the Modern Slavery Act 2015, organisations with a certain turnover must publish an annual modern slavery statement.
This statement should outline:
- The structure of the organisation and its supply chains
- Policies related to slavery and human trafficking
- Due diligence processes
- Risk assessment and management approaches
- Effectiveness of measures taken
The UK Government provides detailed guidance on compliance and reporting through official resources such as GOV.UK.
However, beyond compliance, organisations are expected to demonstrate active risk management—not just disclosure.
How can businesses identify modern slavery risks?
Identifying risk requires a combination of data, due diligence, and awareness.
Key indicators include:
- Suppliers operating in high-risk regions
- Labour-intensive industries (e.g. construction, manufacturing, agriculture)
- Lack of transparency in subcontracting
- Unusually low pricing or cost pressures
Risk mapping is often the first step in understanding:
- Who your suppliers are
- Where they operate
- How labour is sourced
Frameworks like ISO 20400 support organisations in embedding sustainable procurement practices, helping to identify and manage risks within supplier relationships.
What role does due diligence play in managing risk?
Due diligence is central to modern slavery prevention.
Effective due diligence includes:
- Supplier assessments and onboarding checks
- Contractual requirements on labour standards
- Ongoing monitoring and audits
- Clear reporting and escalation processes
- Supplier engagement to constructively address the challenges rather than punishing them
Importantly, due diligence is not a one-time exercise; it must be continuous and adaptive.
Government guidance emphasises that organisations should take a risk-based approach, focusing efforts where the likelihood and impact of harm are highest. It should be noted that incidents of modern slavery in the UK are at an all time high. This is not just a “Developing World” problem.
How can organisations improve supply chain transparency?
Transparency is one of the most effective ways to reduce risk.
This involves:
- Mapping supply chains beyond Tier 1 suppliers
- Engaging directly with suppliers
- Encouraging open reporting of issues
- Using technology to track and monitor supplier activity
While full visibility may not always be possible, improving transparency helps organisations move from reactive to proactive risk management.
What are the challenges in tackling modern slavery?
Despite growing awareness, several challenges remain:
- Limited visibility into lower-tier suppliers
- Cultural and legal differences across regions
- Supplier resistance or lack of cooperation
- Balancing cost pressures with ethical sourcing
There is also the risk of superficial compliance, where organisations focus on reporting rather than meaningful action.
Addressing these challenges requires a shift from box-ticking to genuine engagement.
How are expectations evolving for businesses?
Regulatory and stakeholder expectations are increasing. Organisations are now expected to:
- Demonstrate real impact, not just policies
- Show evidence of risk mitigation
- Engage actively with suppliers
- Align with international standards
This is where frameworks such as ISO 20400 become particularly relevant, offering guidance on integrating ethical and sustainable procurement into business strategy.
What is the real impact of getting this wrong?
Failing to address modern slavery risks can have serious consequences:
- Legal and regulatory action
- Reputational damage
- Loss of investor confidence
- Disruption to supply chains
More importantly, it means failing to protect vulnerable individuals from exploitation.
This is why modern slavery guidance is not just about compliance—it’s about responsibility and accountability.

Final Thoughts
Managing modern slavery risk in complex supply chains is not straightforward.
It requires:
- Awareness
- Structured processes
- Continuous improvement
But most importantly, it requires organisations to move beyond surface-level compliance and take meaningful, informed action.
Because in today’s environment, responsible supply chains are not just expected—they are essential.
