NHS Strikes & Industrial Action Explained

NHS industrial action has been a recurring feature of the news since 2023, and it's easy to come away from headlines with only a partial picture of how it actually works — who's legally allowed to strike, what "life and limb" cover really means, and how the current resident doctors' dispute fits into the wider picture of NHS pay negotiation. This page is orientation, not commentary: it explains the mechanics of NHS industrial action in general, neutral terms, without taking a position on the merits of any particular dispute.

The legal right to strike in the UK

UK workers, including NHS staff, have a general legal right to take part in industrial action, but it isn't unconditional — it depends on the action being organised correctly by a recognised trade union under UK strike law. That legal framework exists specifically to make sure industrial action reflects genuine, demonstrated support among the workforce affected, rather than being called on a whim by union leadership. The core requirements a union has to meet include:

• A postal ballot of all members who'd be asked to take part, run independently of the employer.
• A minimum turnout threshold for the ballot to be valid — a majority of those balloted must actually vote, not just a majority of those who happen to vote.
• A majority "yes" vote among those who do vote, for the action to go ahead lawfully.
• Formal notice to the employer — typically at least two weeks — of the intent to strike, giving the organisation time to plan cover.
• A time limit on how long a ballot mandate stays valid before a fresh ballot is needed if the union wants to call further action.

If any of these steps aren't followed correctly, action isn't legally protected — which is why ballot results, turnout figures and mandate expiry dates tend to get reported alongside strike announcements; they're not just background colour, they're the legal basis for the action being lawful in the first place.

"Life and limb" cover: what it actually means

One of the most misunderstood parts of any NHS strike is what happens to emergency and critical care while it's on. The short version: it doesn't stop. Ahead of a health strike, the relevant union and the affected NHS employer typically negotiate a "life and limb" cover agreement — a voluntary, locally negotiated arrangement under which a defined number of staff in specific roles continue working through the strike, specifically to maintain the kind of care where a total withdrawal of labour could put patients' lives or long-term health at serious, immediate risk. This usually covers things like emergency departments, intensive care, maternity emergencies, and other genuinely time-critical services.

It's important to understand that "life and limb" cover isn't a single fixed national rule with one definition — the specifics (which services, how many staff, which shifts, which grades) are negotiated separately for each individual strike, based on what the union and the trust jointly agree is genuinely safety-critical for that action. This is also why the practical impact of a strike varies so much from one to the next: a strike with generous, broad cover arrangements can look and feel very different on the ground from one with narrower cover, even if both are called by the same union over the same underlying dispute.

What a strike means in practice

For patients

Non-urgent and routine care — many outpatient appointments, planned (elective) procedures, and some diagnostic tests — is the most likely to be postponed or rescheduled around a strike day, because trusts plan ahead to concentrate the staff they do have on genuinely urgent and emergency work. Emergency departments, maternity emergency care, cancer treatment and other safety-critical services are prioritised throughout, generally via the life and limb cover arrangements described above. If you have an appointment scheduled on or near a strike day, your trust should contact you directly if it's affected — don't assume either way without checking.

For NHS staff not striking

Colleagues who aren't part of the striking group — whether because their role wasn't part of the ballot, they're providing life and limb cover, or they've individually chosen not to take part — typically pick up a heavier workload on a strike day, covering wards, clinics and services that would otherwise be short-staffed. Trusts also commonly bring in additional temporary staffing through agency or bank arrangements, redeploy staff from less urgent areas, and postpone non-essential meetings and administrative work to free up clinical capacity. It's a genuinely stretched day operationally for the staff who are in, even though it looks, from the outside, like "business as usual with fewer doctors."

Beyond a full walkout: other forms of industrial action, and how disputes tend to resolve

A full strike day — a total, visible withdrawal of labour — is the form of industrial action that gets by far the most attention, but it isn't the only lawful form a union can take, and disputes don't only end through a strike simply stopping. Two things are worth understanding in general, neutral terms:

• • Action short of a strike (ASOS) — a union can call action that falls short of a full walkout, such as an overtime ban, working strictly to rule, or declining to cover duties outside a normal role, generally under the same legal ballot requirements as a strike itself. This can run for a sustained period and doesn't always make headlines the way a strike day does, but it's a genuine, distinct category of lawful industrial action.
• • Picketing — a lawful, regulated way for striking staff to communicate their position and peacefully encourage others not to work, generally limited to a striker's own workplace and subject to rules intended to keep it peaceful and non-obstructive. It's a visible part of many strike days, but it's a communication tool alongside the strike, not the strike action itself.

Disputes themselves tend to resolve through a small number of general routes, independent of the specifics of any one dispute: direct negotiation between the union and the employer or government resuming and reaching agreement; independent conciliation through a body like ACAS, which can help both sides find common ground without either side having to make the first move publicly; or, for staff groups whose pay goes through a review body process, that body gathering fresh evidence and making a new recommendation. None of these routes is guaranteed to work in any given dispute, and more than one can be tried, in either order, before a dispute is resolved — this is general context on how these processes tend to work, not a prediction about how any current or future NHS dispute will actually play out.

It's also worth understanding that not every NHS pay disagreement turns into a strike, and a strike happening in one part of the NHS doesn't mean the whole workforce is in dispute at once. Most years, most NHS staff groups accept the outcome of the standard Pay Review Body or DDRB process without any industrial action at all — a strike is one possible outcome of a breakdown in that wider negotiating system, not the default or the norm. When strike action does happen, it's generally the product of a specific group's ballot, over a specific dispute, rather than a single NHS-wide event — which is part of why a strike affecting one staff group or union doesn't automatically mean every NHS trust or every profession is striking on the same day.

The resident doctors' dispute in context

Resident doctors — the grade previously known as junior doctors, spanning Foundation Year 1 through to ST6 and above — have taken strike action as part of a pay dispute that's been running since 2023, and it's one of the most sustained periods of industrial action the NHS has seen. The structural reason this dispute has looked different from other NHS pay negotiations is that resident doctor pay sits on its own separate track: it isn't set through the standard NHS Pay Review Body process that covers Agenda for Change staff, and it isn't set through the DDRB process that covers consultants either. Instead, it's been the subject of direct, multi-year negotiation between the BMA and government — and that negotiation has, at various points since 2023, broken down into periods of strike action when talks stalled.

We're deliberately not listing specific strike dates, durations or turnout figures on this page — that level of detail changes as the dispute develops and belongs in a place we can keep precisely current, not baked into a general explainer. For the pay figures, negotiation status, and how this dispute relates to the other NHS pay tracks for 2026/27, see our NHS Pay Rise 2026/27 page, which we update as the situation develops.

Who represents NHS staff in disputes like this

Industrial action is always called by a trade union, not by NHS staff acting individually or collectively outside a union structure — it's the union that runs the ballot, negotiates cover arrangements, and represents members in negotiations with employers and government. Different unions and royal colleges represent different parts of the NHS workforce, and understanding who represents your profession is useful background for making sense of any dispute you read about. See our explainer on NHS staff representation, unions and royal colleges for how that landscape is organised.

Frequently asked questions

Can all NHS staff legally strike? +

Most NHS staff have the same general legal right to take industrial action as other UK employees, provided their union follows the required legal process — a valid ballot, notice to the employer, and so on. In practice, participation varies hugely by role and by union: some professions and grades have historically been far more likely to ballot and strike than others, and individual staff always retain the choice of whether to participate even when their union has a legal mandate to call action. There's no blanket rule banning any single NHS profession from striking, though voluntary 'life and limb' cover arrangements (see below) shape how a strike actually plays out on the ground.

What is 'life and limb' cover? +

It's a voluntary arrangement, agreed locally between a union and an NHS employer ahead of a strike, under which some staff continue working during industrial action specifically to maintain emergency and safety-critical care — the kind of care where a total withdrawal of labour could put patients' lives or long-term health at serious risk. It isn't a single fixed national rulebook; the details (which services, how many staff, which shifts) are negotiated case by case for each strike, based on what the union and the trust agree is genuinely safety-critical for that specific action.

Do NHS staff get paid when they're on strike? +

No. Staff who take part in a legally organised strike are not paid by their employer for the time they're on strike — pay is withheld for the period of the action, the same as for most UK employees taking industrial action. Some unions operate strike funds that can provide limited financial support to striking members, but this comes from the union, not from NHS pay.

Is it legal for the NHS to just sack striking staff? +

Employees taking part in official, properly balloted industrial action have specific legal protections against dismissal for participating, for a protected period defined in UK employment law. Those protections aren't unlimited or indefinite, and the law in this area has specific technical conditions, so this is a genuine area where affected staff should get advice from their union rather than relying on a general summary — but the basic legal position is that lawfully organised strike action carries real employment protections, not none.

Have resident doctors actually gone on strike in the NHS? +

Yes. Resident doctors (the grade previously called junior doctors) have taken strike action as part of the pay dispute that's been running since 2023, one of the most significant periods of industrial action in the NHS's history. We're covering that fact here in general, neutral terms rather than listing specific dates and durations we can't currently stand behind with full confidence — for the pay figures and negotiation status behind the dispute, see our dedicated NHS pay rise page.

Why is the resident doctors' dispute separate from other NHS pay disputes? +

Resident doctor pay has been on its own negotiating track, directly between the BMA and government, separate from both the NHS Pay Review Body process that covers Agenda for Change staff and the DDRB process that covers consultants. That's a structural reason the dispute has run differently — and in some years more visibly through strike action — than pay negotiations for other NHS staff groups, rather than a reflection of the dispute being somehow bigger or smaller in scale than others.

What should I do as a patient if a strike affects my appointment? +

NHS trusts are required to communicate directly with patients whose appointments are affected by planned industrial action, typically rescheduling non-urgent care in advance and prioritising emergency, urgent and safety-critical services throughout. If you have an appointment on a strike day and haven't heard from your trust, contact them directly — don't assume it's cancelled or that it's going ahead without checking.

What is 'action short of a strike' (ASOS)? +

Industrial action doesn't always mean a full walkout. 'Action short of a strike' covers a range of lesser forms of industrial action a union can call instead of, or alongside, a strike — common examples across UK employment generally include an overtime ban, working strictly to contracted hours or to the letter of a job description ('working to rule'), or declining to cover duties outside a person's normal role. Like a strike, ASOS generally needs to follow the same legal ballot process to be lawful. It tends to attract far less media attention than a full strike day, but it's a genuine and sometimes long-running form of industrial action in its own right, and it's worth knowing the term when you see it referenced in NHS pay dispute coverage.

Is picketing legal during an NHS strike? +

Yes, within limits set by UK law — peaceful picketing at or near a striker's own workplace, to communicate information and peacefully persuade others not to work, is a lawful part of organised industrial action, generally subject to rules such as a picket supervisor being present and identifiable, and limits intended to keep picketing peaceful and non-obstructive. It isn't lawful for picketing to involve intimidation, obstruction, or preventing people who choose to work from entering the workplace.

Can I be made to cross a picket line and work as normal? +

No one can be legally forced to take part in a strike, and equally no one can be legally forced to refuse to work because a strike is happening — working normally during a strike, including crossing a picket line, is a lawful individual choice, just as choosing to strike (where you're eligible and your union has a valid mandate) is. Employers can ask non-striking staff to work as normal and can reasonably expect them to attend, but ultimately how an individual colleague chooses to respond to a strike affecting their workplace is a personal decision, not something either side can compel.
