Skilled Workers, Modern Slavery and the Right to Leave an Abusive Employer

A Skilled Worker visa has always carried one uncomfortable feature. The permission to live and work in the UK is tied to a single sponsor. If that employer behaves badly, the worker has had very little room to walk away without putting their own immigration status at risk.

That is now changing, though only for some workers.

The Home Office published Statement of Changes HC 584 on 3 September 2026. Among other things, it inserts a new provision, SW 18.3, into Appendix Skilled Worker. From 8 October 2026, a Skilled Worker who has received a positive conclusive grounds decision through the National Referral Mechanism (NRM) is no longer tied to the employer who sponsored them.

For the remainder of their existing permission, that person can work for any employer, work on a self-employed basis, or volunteer. The one carve-out is that they still cannot work as a professional sportsperson or sports coach.

This is where the detail matters. The change applies to people who have been formally recognised as victims of modern slavery by a Home Office competent authority. A referral on its own is not enough. The protection follows a positive conclusive grounds decision.

The Home Office has described modern slavery in this context as including harsh or degrading working conditions, withheld wages, deception about the terms of a job, intimidation and threats, violence, restricted movement and confiscated passports, often in combination.

One practical point is the speed of decisions. Free Movement has reported that conclusive grounds waiting times fell from over two years in 2024 to 53 days by March 2026. That makes the new rule far more useful than it would have been a couple of years ago, when a worker could have waited longer than their visa lasted.

Not everyone who is badly treated will meet the threshold for modern slavery. The Royal College of Nursing has said the move does not go far enough and has called for all migrant health and care worker visas to be untied from employers. Commentators have also pointed out that the threshold is high and does not easily capture problems such as wage theft or recruitment fee fraud.

So the position for a worker who is being treated unfairly, but who does not fit the definition, has not changed in any meaningful way. If a sponsored worker's employment ends, the Home Office will normally curtail their permission to 60 days, or to the expiry date if that is sooner. In that window they need to find a new sponsor, switch to another route, or leave.

• Keep records. Contracts, payslips, messages, bank statements and any documents the employer is holding.
• Get advice early. Both on immigration status and on employment rights. Unpaid wages and unlawful deductions can be pursued through ACAS early conciliation and the Employment Tribunal, whatever the immigration position.
• Know the support routes. The Modern Slavery Helpline (08000 121 700) offers confidential help, and the Gangmasters and Labour Abuse Authority investigates labour exploitation in some sectors.
• Do not resign in haste. Leaving a sponsor without a plan can start the 60-day clock. The right sequence of steps depends on the facts.

Sponsors should treat this as a reminder rather than a threat. The sponsorship relationship carries real power over another person's status. Clear contracts, accurate pay, no recruitment fees passed to workers and no retention of documents are the baseline.
