Can a Skilled Worker leave an exploitative sponsor after a positive modern slavery decision?

01 · Commencement

The protection begins on 8 October 2026.

HC 584 inserts SW 18.3 with effect from 8 October 2026. Until then, the current Skilled Worker conditions remain in force. Those conditions restrict the person to the sponsored employment, subject to the limited rules for supplementary employment, voluntary work, notice periods and certain other activities.

The Statement provides that applications made before 8 October 2026 are decided under the Rules in force on 7 October 2026. The new protection should therefore not be presented as existing permission before commencement. A person facing immediate risk should obtain safeguarding and employment advice without waiting for the immigration provision to take effect.

The explanatory memorandum describes the purpose as allowing a recognised victim to work for any employer for the remainder of their existing permission and preventing an exploitative sponsor from weaponising the sponsorship system. That purpose informs the practical significance of the rule, but the operative conditions remain those in SW 18.3.

02 · The NRM threshold

Only a positive Conclusive Grounds decision engages SW 18.3.

The National Referral Mechanism is the framework for identifying and supporting potential victims of modern slavery. A Reasonable Grounds decision is the initial threshold. It asks whether there are reasonable grounds to believe that the person is a victim. A positive decision can trigger support while the case is investigated, but it is not the final recognition required by the new immigration rule.

A Conclusive Grounds decision is the later substantive determination. Under the statutory guidance, the decision is made on the balance of probabilities. SW 18.3 requires that decision to be positive. Self-identification, a report to the police, a referral into the NRM or a positive Reasonable Grounds decision may all be important, but none alone meets the new rule.

The distinction matters because a Conclusive Grounds decision may take materially longer than the initial referral stage. During that interval the worker’s existing immigration conditions remain relevant. Immediate safety planning, sick leave, employment remedies, sponsor change options and any other immigration route should therefore be considered rather than assuming that unrestricted work permission will follow quickly.

03 · The timing test

The decision must fall within the most recent Skilled Worker permission.

SW 18.3 is not framed solely by the date of exploitation or referral. The positive Conclusive Grounds decision must have been made during the person’s most recent Skilled Worker permission. The grant dates and the date recorded on the decision are therefore central evidence.

A person may have held successive Skilled Worker grants with the same sponsor, changed sponsor or moved into Skilled Worker from another route. The phrase most recent permission requires the current grant to be identified precisely. A historic positive decision made during an earlier grant should not be assumed to satisfy the condition merely because the person remains a Skilled Worker.

The rule also does not say that the exploitation must have been committed by the current sponsor. The case should nevertheless explain the immigration history, the NRM chronology and why the decision falls within the defined period without asking the caseworker or a new employer to reconstruct it from disconnected records.

04 · Amendment

The NRM decision does not itself rewrite the visa conditions.

The drafting is deliberate: an eligible worker may have the conditions in SW 18.2(b) to (e) amended. The provision does not state that the conditions are automatically amended when the competent authority issues its decision. The worker should obtain and retain evidence that the immigration conditions have in fact been changed.

That evidence is particularly important before starting employment with a new organisation. The new employer must carry out the prescribed right-to-work process and establish the work permitted by the person’s current status. A Conclusive Grounds letter is evidence of the protection decision; it is not a substitute for the Home Office evidence required to establish a statutory excuse against illegal working liability.

If the online status record has not caught up with the decision, the parties should not improvise. They should use the prescribed employer checking process where available, preserve the Home Office record and resolve any inconsistency before work begins. An urgent need for income does not make uncertain permission safe for either party.

05 · Work permitted

Amended conditions can permit work beyond the sponsored role.

Once the conditions are amended, SW 18.3 permits any work, including self-employment and voluntary work. That removes the ordinary restriction tying the person to the sponsored job and the narrow supplementary-employment framework. It can allow a clean departure from the sponsor, interim work and a more considered long-term immigration strategy.

The express exception is work as a professional sportsperson, including as a sports coach. A person cannot use the protection to take such work unless another part of their immigration position independently permits it. The restriction should be applied to the substance of the role, not merely its title.

The amendment concerns work conditions. It does not alter the expiry date of the existing Skilled Worker permission, grant indefinite leave, create a new period of sponsorship or remove the no-public-funds condition in SW 18.2(a). The worker’s financial and immigration plan must therefore extend beyond the immediate freedom to work.

06 · Leaving the sponsor

Safety, employment rights and sponsor reporting must be sequenced together.

Immigration permission does not determine whether employment has lawfully ended. Resignation, dismissal, notice, unpaid wages, whistleblowing, discrimination and protective measures are employment-law questions. The worker may also need urgent safeguarding, accommodation, medical or police support. Those matters should be coordinated without allowing sponsorship administration to dominate the immediate risk assessment.

The sponsor’s reporting duties do not disappear because the worker has received a positive Conclusive Grounds decision. Current sponsor guidance generally requires a change in a sponsored worker’s circumstances to be reported within 10 working days, including where the sponsor stops sponsoring because the worker resigns, is dismissed or is made redundant. The report should be accurate, limited to what the sponsor can properly establish and made within the applicable period.

A sponsor must not use reporting as leverage to suppress a complaint or compel continued labour. Equally, a protection concern does not authorise a sponsor to conceal the end of employment or make a misleading SMS report. Employment, safeguarding, data-protection and sponsor decisions should be owned by the appropriate people and recorded separately.

07 · The new employer

A new employer must verify the amended right to work, not investigate the trafficking decision.

The new employer’s immediate immigration task is to establish the person’s right to work and any restrictions. It should not assume that it needs the complete NRM evidence or details of exploitation. Sensitive information should be requested only where there is a lawful and proportionate reason to process it.

Where the amended conditions permit any work, the new role need not itself be sponsored for the remaining period of that permission. That does not make the employer a sponsor, preserve a future Skilled Worker route or guarantee that the person can remain once the current grant expires.

If the organisation may sponsor the person later, the role, occupation code, salary, sponsor status and application timing should be assessed early. A later Skilled Worker application will be tested under the Rules then in force. The temporary freedom created by SW 18.3 should be used to create options, not to postpone the expiry problem.

08 · Settlement

Unrestricted work does not remove the Skilled Worker settlement requirements.

SW 18.3 amends work conditions; it does not create a separate settlement route. Time during the existing Skilled Worker grant is not converted into another form of permission merely because the conditions change. However, eligibility for indefinite leave still has to be tested against the settlement requirements applying on the date of application.

Under the current Appendix Skilled Worker, the sponsor linked to the applicant’s most recent permission must remain approved and must confirm that the applicant is required for the foreseeable future and will be paid at least the relevant salary. A person who has left the sponsor and is working without sponsorship under amended conditions may be unable to obtain that confirmation.

The practical solution may be a fresh Skilled Worker application with a compliant new sponsor, another route capable of leading to settlement, or a longer strategy that preserves lawful residence while the person rebuilds. None should be assumed. The remaining visa period, qualifying residence already accrued, family position and evidence should be mapped before expiry pressure narrows the choices.

09 · Sponsor governance

Sponsors should treat the change as a safeguarding and governance control.

A responsible sponsor should already have controls capable of detecting recruitment fees, document retention, coercive accommodation, unlawful deductions, excessive hours, threats linked to immigration status and discrepancies between the sponsored role and actual work. SW 18.3 does not create those risks; it changes the worker’s ability to escape them after formal recognition.

Boards and Authorising Officers should ensure that grievance and whistleblowing routes are independent of the line manager controlling sponsorship records. Recruitment agents, connected businesses and labour suppliers require proportionate oversight. A clean sponsor file is not a defence to exploitation occurring outside the documents sampled during a compliance visit.

Where an allegation arises, the sponsor should preserve evidence, protect against retaliation, obtain specialist employment and immigration advice and decide what must be reported to the Home Office or another authority. Internal fact-finding must not obstruct an NRM or criminal process, and a commercial desire for a rapid conclusion should not dictate the worker’s account.

10 · Evidence architecture

The file should prove chronology, conditions and the next lawful step.

The core immigration record should include the current grant and expiry date, evidence of the NRM referral, the Reasonable Grounds decision where relevant, the positive Conclusive Grounds decision and its date, the request or process for amendment, and the Home Office evidence showing the conditions after amendment.

Employment records should be preserved separately: contract, job description, payslips, hours, deductions, communications, grievance material and the evidence surrounding any resignation or dismissal. The worker should receive advice before disclosing sensitive evidence to a prospective employer or allowing an employment dispute to be reduced to an immigration question.

The final strand is forward planning. Record the date by which a new sponsored or alternative application should be ready, whether the present period can contribute to settlement, the evidence a future route will require and any family members whose permission is linked to the worker. The protection works best when immediate freedom and long-term status are treated as 2 different problems.

11 · Counsel judgment

Do not make the worker choose between safety and an untested immigration assumption.

The first question is whether the person is safe. The second is what their current conditions actually permit. The third is how employment, sponsor reporting and future immigration status should be sequenced. Collapsing those questions into a single instruction to resign, remain or change employer creates avoidable risk.

For the worker, the strongest plan identifies the precise NRM stage, secures evidence of any amended conditions, verifies work permission before a new role begins and protects the route beyond the existing expiry date. For the sponsor, the strongest response separates safeguarding and investigation from accurate statutory and sponsor reporting.

Operational Home Office guidance may develop as commencement approaches. Until then, the Rules and the evidence of the individual’s actual conditions should control. Where the position is urgent or the digital record is inconsistent, the answer lies in a documented Home Office process and coordinated advice, not an informal interpretation of the Conclusive Grounds letter.

Practical questions.
