Modern slavery, encompassing forced labour, human trafficking, and other exploitative practices, remains a pervasive global issue impacting every sector, including construction. Construction companies have a crucial role to play in addressing this challenge. 

Besides being a legal requirement for businesses with an annual turnover of over £36 million and operating in the UK, an annual modern slavery statement allows businesses to demonstrate their commitment to tackling this issue.  

But how can a strengthened modern slavery statement support your efforts? 

We analysed the statements of 100 randomly selected large construction companies across the UK against our benchmark. Read on to discover 10 common areas for improvement.   

legal compliance 

#1: Comply with modern slavery statement requirements

We’ve encountered various compliance issues, including publishing modern slavery policies instead of statements, outdated statements on websites, recycled statements, and statements that are difficult to find.  

With new legislation set to hold businesses accountable for non-compliance, these practices can expose your business to significant financial or reputational risks. 

 To comply with the UK Modern Slavery Act, your statement should be: 

  • Published annually, clearly outlining the year covered. 
  • Accessible with a prominent link on your website homepage.
  • Signed by a Director and approved by the Board. 

leadership and governance 

#2: Streamline modern slavery governance

While many modern slavery statements outline strong strategies on paper, ensuring effective implementation in practice is crucial. This requires clear lines of responsibility and accountability, something we often found lacking in the statements we reviewed.  

Your modern slavery statement should:  

  • Clearly outline who within your organisation is responsible for handling modern slavery concerns. Consider using diagrams, like an organogram, to illustrate ownership and how different teams contribute to your strategy. 
  • Share details about your modern slavery working group, if applicable, including meeting frequency, key discussion points, and any standing agenda items. This demonstrates ongoing commitment and collaborative approach.

policies and procedures

#3: Establish clear grievance mechanisms

Enabling a safe, and accessible reporting environment is crucial for workers to feel empowered to raise concerns and seek confidential support when required. This fosters trust and strengthens your anti-slavery approach. 

However, our review revealed a lack of information on companies’ grievance mechanisms, how these are communicated to workers, or whether anonymous whistleblowing channels exists. To enhance your statement, consider: 

  • Providing a detailed explanation of your grievance mechanisms and reporting channels.  
  • Outlining steps taken to ensure clear communication of these mechanisms to your entire workforce. This includes translating information into relevant languages and utilising various communication channels to reach all employees effectively.  

Top tip: If your grievance policy suggests workers report any concerns to HR or senior leadership, consider implementing an external, confidential whistleblowing line. This ensures your workers feel safe to report concerns anonymously

#4: Identify and address modern slavery cases

While outlining grievance procedures in modern slavery statements is crucial, failing to identify modern slavery cases in high-risk sectors like construction might raise questions.  

Instead of assuming your company is low risk, it may highlight a need to assess: 

  • How workers are informed about your whistleblowing line.  
  • How your policies and processes are communicated to workers. 
  • Whether there is a disconnect between your policies and how they work in practice. 

Finding potential cases isn’t necessarily an indicator of a flawed system. It can reflect effective risk identification, active due diligence, and most importantly, your commitment to actively tackling modern slavery. 

The bottom line: If you aren’t identifying any cases, you aren’t looking hard enough.

due diligence

#5: Strengthen supplier due diligence processes

While many modern slavery statements outline supplier expectations and code of conduct requirements, demonstrating adherence to these requirements goes beyond signing documents.  

Consider these crucial questions: 

  • How can you be sure suppliers read and adhere to your policies? 
  • What processes are in place to monitor and enforce adherence to your policies and Code of Conduct? 

Conducting due diligence on due diligence processes is complex, requiring resources and expertise.

However, your modern slavery statement can be an effective tool to outline the strategies used to assess supplier commitment to ethical practices, and how this determines decision-making going forward. 

#6: Enhance on-site worker engagement

Our review noted many companies not implementing on-site due diligence practices to reduce the risk of worker exploitation on site. This includes: 

  • Conducting a two-step verification of worker bank details.  
  • Requiring proof of contracts and pay rates.  
  • Requiring sub-contractors to use PAYE workers. 
  • Conducting payslip spot-checks. 

It is crucial that companies are aware of the key areas on site. Companies lacking on-site worker due diligence processes or robust worker engagement strategies should consider valuable risk mitigation strategies.

#7: Expand supply chain scrutiny

Modern slavery can occur anywhere, making all companies susceptible. Sourcing from well-known or UK-based suppliers doesn’t reduce risk. 

Upcoming legislation will require deeper supply chain scrutiny beyond direct suppliers and UK-based entities, extending to lower tiers. Relying on the fact your tier 1 suppliers are UK-based won’t be enough. 

To demonstrate compliance and understanding of modern slavery risk in your organisation and supply chain, your modern slavery statement should: 

  • Outline any modern slavery risk assessments undertaken across your business and suppliers. 
  • Highlight identified risks and actions taken to address them.

#8: Rethink “zero-tolerance” terminations

While modern slavery statements often express a “zero-tolerance” stance against modern slavery, relying on contract termination in response to potential cases, this approach can backfire. 

It can both increase risk to potential victims and further obscure your supply chain visibility, achieving the exact opposite of its aim. If contract termination is guaranteed for reporting a potential case, why would a supplier report it? 

Building strong supplier relationships and fostering supply chain transparency are key to effective risk management. Your onboarding documents and supplier code of conduct should: 

  • Outline supplier responsibility for identifying and reporting potential modern slavery cases. 
  • Demonstrate your commitment to supporting suppliers in mitigating and remediating identified cases. 

For large organisations, consider sharing resources with small businesses to strengthen their capacity. 

training and awareness 

#9: Enhance modern slavery training details

Modern slavery training is one of the best ways to raise awareness and help build modern slavery considerations into business practices. Yet, while many statements mentioned staff training, details were often lacking. 

Show the following in your statement:  

  • Mandatory modern slavery training.  
  • Role-specific training. 
  • Number of people trained and frequency of refresher training. 
  • Any collaborative training with NGOs or consultants.

key performance indicators

#10: Set measurable KPIs for greater impact

Large companies have the power to drive positive change in the construction industry. Setting clear and measurable modern slavery KPIs for the coming year demonstrates your commitment to addressing the issue. 

However, many companies often miss this opportunity.  This included setting weak goals focused solely on compliance (eg ‘we will publish a modern slavery statement annually’) or withholding KPIs entirely, limiting accountability.  

Strengthen your modern slavery statement by setting strong KPIs: 

  • Quantify progress: use measurable data points to track progress like training completion rates or supplier audits completions. 
  • Demonstrate accountability: include KPIs for public transparency.

As I came to understand more about the issue, including through a visit to an Unseen safehouse, I knew I needed to do more to stop this abuse and exploitation.

For the last five years of my Civil Service career, I was the Modern Slavery Senior Policy Advisor in the Home Office and led on development of the Modern Slavery Act, including the transparency in supply chains provision and business guidance.

I joined Unseen to lead the development of the Modern Slavery & Exploitation Helpline, and Unseen’s work with businesses. I am regularly called upon to present at national and international conferences and use my experience of working with Ministers to influence other governments internationally to take action to address modern slavery and, in particular, business supply chain issues.

In my spare time I enjoy keeping fit, music, reading and travelling.

What ultimately compelled me to act was a report on how people from Eastern Europe were being trafficked through Bristol airport to the USA. Kate Garbers, who went on to be an Unseen Director, and I wrote to all the city councillors, MPs and the Police Chief Constable challenging them on the issue. The challenge came back to us: this city needs safe housing for trafficked women. And so Unseen began.

But we never wanted Unseen to be just about safe housing. We wanted to end slavery once and for all, and that remains our driving focus.

I chaired the working group for the Centre for Social Justice’s landmark report “It Happens Here: Equipping the United Kingdom to Fight Modern Slavery”. This is now acknowledged as the catalyst behind the UK’s Modern Slavery Act of 2015. It was a great honour to be awarded an OBE in the Queen’s Birthday Honours that year. On the other hand, I’ve also been described as “the loveliest disrupter you could ever hope to meet”.

This job has taken me from building flat-pack furniture for safehouses, to working with businesses to address slavery in supply chains, to delivering training, raising awareness and advising governments around the world.

When not at work, I enjoy travelling, spending time with my dog Harley, cooking, supporting Liverpool and Yorkshire CC, music (I’m a former DJ) and endurance events such as the Three Peaks Challenge and Tribe Freedom Runs – which I vow never to do again. Until the next time.
