Modern slavery and human trafficking
Modern slavery and human trafficking

Increase your knowledge and understanding of modern slavery and human trafficking to help you spot the signs and act on them. This resource offers you safe steps to take in supporting someone who’s experienced emotional or psychological harm and distress.
What is modern slavery?
Someone is in slavery if they are:
- forced to work – through coercion, or mental or physical threat
- owned or controlled by an ’employer’, through mental or physical abuse or the threat of abuse
- dehumanised, treated as a commodity or bought and sold as ‘property’
- physically constrained or have restrictions placed on their freedom of movement.
What is human trafficking?
Human trafficking involves recruitment, harbouring or transporting people into a situation of exploitation through the use of violence, deception or coercion and forced to work against their will.
(Slavery in the UK, Anti-Slavery International)
An estimated 50 million men, women, and children are victims of modern slavery. Of these, an estimated 28 million people are in forced labour and 24 million people are living in a forced marriage.
The UK Government estimates that around 10,000 people in the UK are affected by modern slavery. However, current estimates do not cover all forms of modern slavery, for example, organ trafficking, child soldiers, or child marriage (forced marriage). Therefore, numbers may not be accurate and experts believe this figure to be more like 122,000 people.
What to do if you spot the signs
If you suspect that a person is a victim of slavery, this is a safeguarding issue.
You should trust and act on your professional instinct that something is not quite right. It is usually a combination of triggers, an inconsistent story and a pattern of symptoms that may cause you to suspect trafficking.
If you have any concerns about a child, young person or adult take immediate action to ask further questions and get additional information and support. It is important to remember that:
- trafficked people may not self-identify as victims of modern slavery
- trafficking victims can be prevented from revealing their experience to health care staff from fear, shame, language barriers and a lack of opportunity to do so. It can take time for a person to feel safe enough to open up
- err on the side of caution regarding age. If a person tells you they are under 18 or if a person says they are an adult, but you suspect they are not, then take action as though they were under 18 years old
- support for victims of human trafficking is available.
Psychological First Aid
Many people have some basic first aid training to help someone who has been physically hurt. However, what steps can you take to take to support someone who has experienced emotional or psychological harm and distress? This is particularly important in the settings of severe adversity, after a disaster or in conflict, or the aftermath of the COVID-19 pandemic.
Find further information on training psychological first aid:
- UNICEF: How to provide psychological first aid.
- GOV.UK: Psychological first aid in emergencies training for frontline staff and volunteers.
- GOV.UK: Psychological first aid supporting children and young people affected by coronavirus (COVID-19).
People who suffer in modern slavery and trafficking situations are likely to have significant psychological trauma and may benefit from psychological first aid. This should be followed up with access to secondary mental health care.

Next steps
There are a number of steps you can take if you have identified someone is a victim of trafficking:
- try to find out more about the situation and speak to the person in private without anyone who accompanied them
- when speaking to the person reassure them that it is safe for them to speak
- do not make promises you cannot keep
- only ask non-judgmental relevant questions
- allow the person time to tell you their experiences
- do not let concerns you may have about challenging cultural beliefs stand in the way of making informed assessments about the safety of a child, young person or adult.
- speak to your manager, colleagues or local safeguarding leads for support and advice
- do not raise your trafficking concerns with anyone accompanying the person
- think about support and referral.
