The Recruiter’s Complete Guide to Modern Slavery and Labour Exploitation in the UK

Modern slavery is something no recruiter wants to encounter. However, labour exploitation can sometimes be hidden within recruitment supply chains, making it an issue every agency should understand.

Recruitment professionals play an important role in protecting workers and promoting fair employment practices. The decisions made during the recruitment process can help prevent exploitation, identify concerns early and ensure workers are treated fairly from day one. 

In this guide, we explain what modern slavery can look like in recruitment, outline key legal responsibilities for agencies and share practical steps you can take to reduce risk within your organisation. 

What Does Modern Slavery Look Like in Recruitment?

Modern slavery is an umbrella term used to describe serious forms of exploitation, including slavery, servitude, forced or compulsory labour and human trafficking. 

It is important to understand that modern slavery does not always look the way people might expect. In many cases, workers are not physically prevented from leaving a role. Instead, control can be exercised through debt, intimidation, threats, withholding documents or dependence on others for employment, accommodation or transport. 

As recruiters, we are often the first point of contact for workers entering employment. That places our industry in a unique position to help identify concerns early and support responsible recruitment practices. 

Common Forms of Labour Exploitation

Labour exploitation can take several different forms. Understanding the most common risks can help recruiters recognise potential warning signs. 

Forced Labour

Forced or compulsory labour is work or service exacted under the threat of a penalty and not offered voluntarily. The threat can include violence, dismissal, deportation, withholding wages or other financial or psychological penalties. 

Debt Bondage

Debt bondage can arise when workers are required to repay recruitment costs, travel expenses, accommodation charges or other fees. The debt can become difficult or impossible to clear, leaving the worker trapped in a cycle of dependency. 

Human Trafficking

Under the Modern Slavery Act 2015, human trafficking involves arranging or facilitating a person’s travel with a view to exploitation. This can include recruiting, transporting, transferring, harbouring or receiving a person, and it can occur internationally or entirely within the UK. 

Servitude and Dependency Arrangements

Some workers may rely on the same person or organisation for work, housing and transport. This level of dependency can create opportunities for exploitation and excessive control. 

Wider Labour Abuse 

Issues such as underpayment, unlawful deductions, excessive working hours and unsafe working conditions may not always meet the legal definition of modern slavery. However, they can be indicators of wider labour exploitation and should never be overlooked. 

While some sectors are considered higher risk, including agriculture, food processing, construction, hospitality, social care and logistics, exploitation can occur in any industry. 

Understanding Your Legal Responsibilities

For recruitment agencies operating in England and Wales, the principal legislation is the Modern Slavery Act 2015. Scotland and Northern Ireland have separate trafficking and exploitation legislation. 

  • Slavery, servitude, forced labour and human trafficking are criminal offences. 
  • Commercial organisations carrying on business in the UK, supplying goods or services and with total turnover of at least £36 million must publish a slavery and human trafficking statement for each financial year under Section 54 of the Act. 
  • Many clients require suppliers and recruitment partners to demonstrate their approach to tackling modern slavery, even when they are not legally required to publish a statement themselves. 

There are also other areas of legislation that recruiters should be familiar with. 

Employment Agency Regulations

Recruitment agencies and employment businesses in Great Britain must comply with the Employment Agencies Act 1973 and the Conduct of Employment Agencies and Employment Businesses Regulations 2003, as amended. These rules protect work-seekers and set standards for agency conduct. Northern Ireland has a separate regulatory regime. 

Minimum Wage and Deductions

Recruiters should be alert to any arrangements that could result in workers being paid below the National Minimum Wage, particularly where accommodation, transport or other charges are involved. 

Right to Work Checks 

Right to work checks are designed to establish whether a person is legally permitted to work and, when carried out correctly, can provide an employer with a statutory excuse against a civil penalty. They do not establish whether a worker is being exploited, so separate safeguarding and welfare checks remain necessary. 

Gangmasters Licensing and the Fair Work Agency

Recruitment agencies supplying workers in agriculture, horticulture, shellfish gathering and associated food processing and packaging must hold the relevant gangmasters licence. It is a criminal offence to act as a gangmaster without a licence or to use an unlicensed gangmaster. Recruiters should check the public register and keep licence status under review. 

This article provides general information and should not be considered legal advice. If you are unsure about your obligations, seek professional legal guidance. 

Warning Signs Recruiters Should Be Aware Of

A single concern may not indicate exploitation. However, patterns of behaviour can highlight potential risks that deserve further attention. 

Worker-Related Warning Signs
  • Identity documents are held by another person. 
  • The worker is unsure who they work for or how they are being paid. 
  • They owe money to a recruiter, accommodation provider or transport provider. 
  • They appear reluctant to speak openly or are always accompanied by someone else. 
  • Multiple workers use the same bank account or address. 
  • Their pay differs significantly from what was originally agreed. 
Client and Supplier Warning Signs
  • Labour costs appear unrealistically low. 
  • Information about payroll, subcontractors or working conditions is difficult to obtain. 
  • Large groups of workers are supplied through a single intermediary. 
  • There is pressure to bypass normal recruitment processes or checks. 
  • Accommodation and transport deductions cannot be clearly explained or verified. 

If something does not seem right, trust your professional judgement and investigate further. 

Practical Steps for Responsible Recruitment

The most effective approach is to build modern slavery prevention into your everyday recruitment processes. 

  1. Assess Your Risks 

Review the sectors you recruit for, the locations you operate in and any third-party organisations involved in your recruitment process. Identify where risks may be higher and document your findings. 

  1. Never Charge Recruitment Fees to Workers 

Recruitment agencies and employment businesses must not charge work-seekers for work-finding services, subject to limited statutory exceptions for certain occupations. Do not make access to work conditional on buying other services and ensure recruitment partners follow the law and responsible-recruitment standards. 

  1. Carry Out Due Diligence 

Take time to understand how your clients, suppliers and recruitment partners source labour. Ask questions and keep clear records of the answers provided. 

  1. Provide Clear Information 

Ensure workers receive clear terms and conditions before they start work. Wherever possible, information should be provided in a language they understand. 

  1. Monitor Pay and Deductions 

Regularly review payslips, deductions and accommodation arrangements to ensure workers are being treated fairly and paid correctly. 

  1. Speak Directly to Workers 

Creating opportunities for private conversations can help workers raise concerns they may not feel comfortable discussing in front of supervisors or intermediaries. 

  1. Train Your Colleagues 

Everyone involved in recruitment, onboarding, payroll and worker support should understand the signs of exploitation and know how to escalate concerns. 

  1. Establish a Clear Reporting Process 

Make sure your organisation has a clear process for recording concerns, investigating issues and deciding on appropriate next steps. 

  1. Review Regularly 

Modern slavery risks can change over time. Review risk assessments, due-diligence records, training and reporting procedures regularly, and whenever your sectors, locations, clients or labour-supply arrangements change.

Frequently Asked Questions About Modern Slavery in Recruitment

What is modern slavery in recruitment?

Modern slavery in recruitment refers to situations where individuals are recruited or employed under conditions of exploitation. This can include forced labour, debt bondage, servitude and human trafficking. While some cases involve threats or coercion, others are less obvious and may involve financial control, withheld documents or excessive dependency on an employer or intermediary. 

What are the warning signs of labour exploitation?

Common warning signs include workers having their identity documents held by someone else, sharing bank accounts, owing money to recruiters or accommodation providers, being unable to explain their pay arrangements or appearing reluctant to speak on their own. A single indicator may not be cause for concern, but several warning signs together warrant further investigation. 

Are recruitment agencies legally responsible for preventing modern slavery?

Recruitment agencies must comply with the laws applying to their activities and should remain alert to signs of exploitation. Section 54 requires qualifying commercial organisations to publish an annual slavery and human trafficking statement; it does not impose a general legal duty on every recruitment agency to guarantee that modern slavery is prevented. Clients may also require recruitment partners to demonstrate robust prevention processes. 

Can modern slavery happen in any industry? 

Yes. Although sectors such as agriculture, construction, hospitality, logistics and social care are often considered higher risk, labour exploitation can occur in any industry where vulnerable workers may be targeted. 

What should recruiters do if they suspect exploitation?

If someone is in immediate danger, call 999. For non-emergency concerns, record factual information and follow your organisation’s safeguarding and escalation procedures. You can contact the police on 101 or report to the Modern Slavery & Exploitation Helpline on 08000 121 700 or online. Only designated First Responder Organisations can refer potential victims into the National Referral Mechanism; follow your organisation’s referral pathway. 

How can recruiters reduce the risk of modern slavery?

Good practice includes carrying out due diligence on clients and suppliers, ensuring workers are not charged recruitment fees, reviewing pay and deductions, speaking directly with workers, training colleagues to spot warning signs and regularly assessing risks within recruitment processes. 

Building a Culture of Responsible Recruitment 

Preventing modern slavery is not about introducing unnecessary complexity into your recruitment process. 

We recommend starting with one area of your business, whether that is worker welfare checks, partner vetting or payroll reviews, and building from there. Small improvements made consistently can have a significant impact.
