The Home Office has introduced a new protection allowing recognised victims of modern slavery on Skilled Worker visas to leave an exploitative sponsoring employer and work elsewhere without losing their existing immigration permission.
The change is designed to remove one of the most serious barriers faced by migrant workers who report exploitation: the risk that walking away from the employer sponsoring their visa could also jeopardise their ability to remain in lawful employment.
Under the new arrangement, people who are formally recognised as victims of modern slavery through the National Referral Mechanism can work for another employer for the remainder of their existing Skilled Worker visa.
The measure is therefore not a general right for all sponsored workers to change employer freely. It applies to the specific group of workers recognised through the modern-slavery system.
Victims no longer tied to alleged exploiter
The sponsorship system normally links a Skilled Worker’s immigration permission to the job and licensed sponsor specified when their visa is granted.
Under the ordinary rules, a Skilled Worker changing employer generally needs a new Certificate of Sponsorship and must make a fresh change-of-employment application before beginning the new sponsored job.
That arrangement has created a particular problem in cases involving labour exploitation. A migrant worker may be legally entitled to complain about abusive conditions but can face a difficult practical choice if leaving the employer also puts their immigration status and income at risk.
The new Home Office protection is intended to break that dependency for recognised modern-slavery victims.
National Referral Mechanism is key safeguard
The change should not be interpreted as meaning that an allegation against an employer automatically removes the conditions attached to a Skilled Worker visa.
The National Referral Mechanism (NRM) is the UK framework for identifying and supporting potential and confirmed victims of modern slavery.
Cases are referred to the system by authorised first-responder organisations and considered by a competent authority.
Modern slavery can include human trafficking, slavery, servitude and forced or compulsory labour. Home Office guidance also makes clear that poor employment conditions or minimum-wage breaches do not automatically amount to modern slavery.
Care sector exploitation has driven concern
The reform comes after repeated concerns about the treatment of some overseas workers recruited to Britain under sponsored visa routes, particularly in adult social care.
The Government’s immigration white paper acknowledged reports of unethical and exploitative recruitment and employment practices affecting international care workers.
It said some workers already in Britain remained vulnerable to exploitation by unscrupulous sponsors and promised to examine reforms making it easier for sponsored workers to move between employers.
The white paper also recorded 1,494 Skilled Worker sponsor-licence revocations during 2024, compared with 337 during 2023.
Legal challenge exposed problem with existing rules
The policy change also follows legal pressure over the position of trafficking survivors who already held valid Skilled Worker permission.
In August, the Home Office accepted during litigation that officials had discretion to vary existing immigration leave so recognised trafficking survivors could be considered for temporary permission associated with their status as victims.
The broader policy announced now gives recognised victims a more direct route to continue working without remaining dependent upon the original sponsor.
Ordinary Skilled Worker rules remain in place
For sponsored workers who are not covered by the modern-slavery protection, the standard immigration rules remain in force.
Home Office Skilled Worker guidance states that a person changing employer normally has to make a change-of-employment application, provide a new Certificate of Sponsorship from the new sponsor and continue to meet the relevant visa requirements.
That distinction is significant because the new measure does not turn the Skilled Worker visa into an unrestricted work visa.
Instead, it creates a specific safeguarding exception intended to ensure that formally recognised victims are not forced to choose between staying with an exploitative employer and losing their ability to work lawfully.
Government had promised sponsorship reform
The Government has already indicated that wider changes to the sponsorship system could follow.
Its immigration white paper said ministers would explore making it easier for workers to move between licensed sponsors for the duration of their visas, arguing that greater mobility could give workers more control and reduce their vulnerability to exploitation.
The modern-slavery measure goes further for a narrower category of people by removing the immediate dependency on the original sponsor once the worker has been recognised through the relevant process.
Its practical impact will depend in part on how quickly victims are identified through the National Referral Mechanism and how easily workers are able to demonstrate their new right to work to prospective employers.
