Changes to the UK Immigration Rules have introduced new protections for certain Skilled Worker visa holders who are victims of modern slavery, human trafficking or forced labour.
The changes are intended to reduce the risk that migrant workers remain in exploitative employment because their immigration status is linked to their sponsoring employer.
For eligible workers, the new provisions provide greater flexibility to leave an exploitative employment situation and seek alternative work in the UK.
This article explains the new protection, who it may apply to, how the National Referral Mechanism (NRM) is involved, and what Skilled Workers should consider if they are experiencing workplace exploitation.
What Has Changed for Skilled Worker Visa Holders?
The Skilled Worker route normally requires a migrant worker to work in the role and for the employer connected to their sponsorship.
This employer-specific arrangement can create difficulties where the employment relationship breaks down, particularly where a worker is experiencing serious exploitation.
The latest changes provide an important safeguard for workers who are formally identified as victims of modern slavery, human trafficking or forced labour.
In qualifying circumstances, the worker can benefit from greater flexibility to leave the exploitative sponsor and undertake alternative employment for the remaining period of their permission.
The change is particularly important because immigration status can otherwise create a significant dependency on the sponsoring employer.
Why Has the Government Introduced This Protection?
Migrant workers can be particularly vulnerable to exploitation where their right to work is connected to a specific sponsor.
An employer may attempt to use that dependency to discourage a worker from reporting unlawful treatment or leaving their employment.
Examples of potentially serious indicators can include:
- Threats relating to immigration status or deportation
- Confiscation or control of identity documents
- Unlawful recruitment fees or deductions
- Debt used to control a worker
- Withholding wages
- Excessive or coercive working conditions
- Threats of harm or other forms of intimidation
However, an employment dispute or breach of employment law will not necessarily amount to modern slavery or trafficking.
The circumstances and evidence must be considered on their individual facts.
Who Could Benefit From the New Rules?
The protection is relevant to Skilled Worker visa holders who are identified through the appropriate process as victims of modern slavery, human trafficking or forced labour.
It is not limited to one particular occupation.
However, the change may be particularly significant for migrant workers employed in sectors where concerns about exploitation and recruitment practices have received increased attention.
Health and Social Care Workers
Care workers and other migrant employees in the social care sector may face particular vulnerabilities where recruitment debts, unlawful deductions or threats are involved.
Where the circumstances meet the relevant modern slavery or trafficking threshold, the new protections may become relevant.
Hospitality Workers
Sponsored chefs and other hospitality workers can also potentially benefit where serious exploitation is identified.
Issues such as withheld wages, debt, coercion and threats may be relevant depending on the circumstances.
Other Sponsored Workers
The protection is not restricted to care or hospitality.
A Skilled Worker in another occupation may also be covered where they meet the relevant requirements.
The National Referral Mechanism
The National Referral Mechanism (NRM) is the UK’s framework for identifying and supporting potential victims of modern slavery and human trafficking.
The NRM can therefore be an important part of the process for a Skilled Worker seeking protection under the new provisions.
Adults generally cannot make an NRM referral entirely independently. A referral is normally made by an authorised First Responder Organisation, with informed consent required for adult referrals.
First Responders can include organisations such as:
- Police forces
- Local authorities
- The Gangmasters and Labour Abuse Authority (GLAA)
- Certain specialist organisations and charities
What Happens After an NRM Referral?
The modern slavery identification process involves two principal decisions.
Reasonable Grounds Decision
The first stage is the Reasonable Grounds assessment.
This considers whether there are reasonable grounds to believe that the person may be a victim of modern slavery.
A positive Reasonable Grounds decision can be particularly important for an affected Skilled Worker because it can activate relevant immigration protections under the updated framework.
Conclusive Grounds Decision
The second stage is the Conclusive Grounds decision.
This involves a more detailed consideration of the circumstances and available evidence to determine whether the individual should be conclusively identified as a victim.
The two stages should therefore not be confused.
A Reasonable Grounds decision is an initial assessment; it is not the final determination of the case.
What Evidence May Be Relevant?
There is no single piece of evidence that automatically establishes exploitation.
Instead, the authorities may consider the overall circumstances.
Relevant evidence may include:
Employment records: contracts, payslips, working-hour records and correspondence with the employer.
Financial evidence: deductions, recruitment charges, loans or other debts connected with obtaining employment.
Communications: messages or emails containing threats, intimidation or instructions relating to immigration status.
Identity documents: evidence concerning the retention or control of passports or other documents.
Working conditions: information about hours, accommodation, wages and restrictions imposed on the worker.
Workers should only collect or preserve evidence where it is safe to do so.
What Does the Change Mean in Practice?
The key practical point is that an eligible Skilled Worker should not necessarily have to remain with an exploitative sponsor simply because their immigration permission is connected to that employer.
The new framework provides a mechanism through which qualifying victims can obtain protection while moving away from the circumstances of exploitation.
This is an important distinction from the ordinary Skilled Worker position, where changing employment generally requires compliance with the sponsorship and immigration requirements applicable to the new role.
The protection therefore addresses a specific vulnerability within the sponsorship system rather than creating a general right for all Skilled Workers to change employer or occupation without restriction.
What Should a Skilled Worker Do If They Are Being Exploited?
Anyone experiencing serious exploitation should consider obtaining specialist advice as soon as possible.
Depending on the circumstances, appropriate organisations may include the police, local authorities, GLAA or specialist modern slavery organisations.
Immigration advice may also be appropriate, particularly where leaving employment could otherwise affect the individual’s immigration position.
Workers should avoid assuming that simply leaving their sponsored employment automatically gives them permission to work for another employer.
The new protection has specific requirements, and individual circumstances need to be assessed carefully.
What Employers Should Know
The changes also reinforce the importance of employers understanding their responsibilities towards sponsored workers.
A sponsor licence does not give an employer unlimited control over a migrant worker.
Employers should ensure that employment practices comply with relevant UK employment and immigration requirements and should not use a worker’s immigration status as a means of coercion or control.
Where serious exploitation is identified, employers may also face consequences beyond the individual’s immigration position.
Frequently Asked Questions
Can a Skilled Worker leave an abusive sponsor?
Where the worker is covered by the new protection and the relevant requirements are met, they may be able to leave the exploitative employment and benefit from immigration flexibility allowing alternative employment.
The position should be assessed before taking action because ordinary Skilled Worker rules continue to apply where the special protection does not apply.
Does every employment dispute qualify as modern slavery?
No.
Unfair treatment, an employment dispute or a breach of employment law does not automatically amount to modern slavery, trafficking or forced labour.
The facts and evidence must be considered against the relevant legal framework.
Can a Skilled Worker self-refer to the NRM?
Adults generally require a referral through an authorised First Responder Organisation rather than making a direct referral themselves.
What is a Reasonable Grounds decision?
It is the initial NRM decision assessing whether there are reasonable grounds to believe that an individual may be a victim of modern slavery.
What is a Conclusive Grounds decision?
It is the later, more detailed decision concerning whether the individual should be conclusively identified as a victim of modern slavery.
Does this protection apply only to care workers?
No.
Although care workers may be among those who could benefit significantly from the protection, the provisions can apply more broadly to eligible Skilled Workers who are victims of qualifying exploitation.
Conclusion
The September 2026 changes represent an important development in the relationship between the UK’s sponsorship system and protections for migrant workers.
For Skilled Workers experiencing modern slavery, human trafficking or forced labour, the new framework may provide an important route away from exploitative employment without leaving them without immigration protection.
The rules are, however, specific and fact-sensitive. A worker should not assume that leaving their sponsor automatically gives them permission to work elsewhere.
Anyone concerned about exploitation or their immigration status should obtain appropriate immigration and safeguarding advice based on their individual circumstances.
