Working Hours, Rest Breaks, Holiday and Sick Pay in the UK

Working time in the UK is regulated, and the rules are more generous in some respects and more flexible in others than workers arriving from elsewhere expect. The parts people most often do not know about are the ones that cost them money — rest breaks, holiday accrual on irregular hours, and sick pay.

This article covers what the law provides and what to check about your own arrangement.

It is general information, not legal advice. Rules change and apply differently to different arrangements. Free authoritative advice is available from the conciliation service linked below.

Working hours

UK working time rules set a limit on average weekly working hours, calculated over a reference period rather than week by week. Workers can agree to opt out of that limit, and the opt-out must be voluntary and in writing.

Two points matter. An opt-out is a choice, not a condition of employment, and pressure to sign one is worth questioning. And you can generally withdraw from an opt-out, with notice.

There are also rules on night work, including limits and health assessments, and special provisions for young workers.

Rest breaks and rest periods

The entitlements here are specific and widely ignored in practice.

Adult workers are generally entitled to a rest break during the working day where the day exceeds a defined length, to a daily rest period between working days, and to a weekly rest period.

Two things to check. Whether your break is paid or unpaid — it is commonly unpaid, and that affects your hourly arithmetic. And whether you are genuinely free during it, because a “break” during which you must remain available may count as working time.

Holiday, including for irregular hours

Statutory paid holiday applies to workers as well as employees, and this is the entitlement most often lost by people on agency, casual or part-time arrangements who assume it does not apply to them.

Entitlement accrues with the hours worked, so irregular and part-time workers have a proportionate entitlement rather than none. Rules on how it is calculated for irregular hours, and on carrying leave over, are specific and have been subject to change.

Check your holiday year, how you request leave, and what happens to untaken holiday. On leaving, you are generally entitled to payment for accrued untaken holiday — ask for that calculation in writing.

Sick pay

Statutory Sick Pay is available to eligible employees who are off work sick, subject to conditions including qualifying earnings and a period before it becomes payable. Some employers offer contractual sick pay that is more generous — check what yours provides, because the difference is substantial.

The practical steps matter as much as the entitlement. Notify your employer according to the procedure in your contract, promptly. For shorter absences self-certification is usual; for longer ones a fit note from a healthcare professional is generally required.

Most sick pay disputes are really disputes about notification, so follow the procedure exactly and keep a record of what you sent and when.

Other leave you may not know about

UK law provides a range of family and other leave entitlements, including maternity, paternity, adoption and shared parental leave, unpaid parental leave, and time off for dependants in emergencies. Eligibility conditions apply to each.

If any of these could affect you, check the official guidance rather than relying on what a colleague says, because the eligibility rules are specific and the amounts differ.

Zero hours and irregular arrangements

These are common in the sectors many new arrivals work in, and they deserve their own treatment.

A zero hours arrangement means no guaranteed hours. Workers on them still generally have worker rights including the minimum wage and paid holiday, which is the fact most often not understood.

What to establish: whether any hours are guaranteed, how shifts are offered and whether you can decline, whether you may work elsewhere, and how holiday is calculated on irregular hours.

The financial reality is the harder part. Income that varies week to week makes budgeting and renting difficult, and it is worth being honest with yourself about that before accepting an arrangement where nothing is guaranteed.

Keeping your own record

Every dispute about hours, breaks, holiday or sick pay is decided on records, and the employer holds them by default.

Keep a note of shifts worked — date, start, finish, breaks taken and whether paid. Keep your rotas. Check them against your payslip each month, and raise any discrepancy in writing that month.

This takes a minute a day and it is the difference between raising a specific point with dates and saying that something felt wrong.

If something is wrong

Raise it with your employer first, in writing. Most problems are administrative and resolve there.

If they do not, free and impartial advice on employment rights is available from the conciliation service, which also has a role before a claim can be brought to an employment tribunal.

Employment protections apply in many respects regardless of immigration status, and being pressured with your visa to accept unlawful treatment is a marker of an employer operating outside the rules.

Frequently asked questions

Can my employer make me work more than the weekly limit? The opt-out must be voluntary and in writing, and you can generally withdraw from it with notice.

Are breaks paid? Commonly unpaid, though you must genuinely be free during them. Check your contract.

Do I get holiday on a zero hours contract? Workers accrue paid holiday with the hours they work. This is widely misunderstood.

How do I claim sick pay? Follow your employer notification procedure promptly, self-certify for short absences and obtain a fit note for longer ones.

What if my employer refuses my entitlements? Raise it in writing, then take free advice from the conciliation service.

The habit worth forming

Record your shifts, check them against your payslip monthly, know your holiday year, and follow the sickness notification procedure exactly. Those four habits protect nearly everything this article describes.

The 48-hour week and what an “opt-out” really signs away

The Working Time Regulations cap the average working week at 48 hours, averaged over a rolling 17-week reference period rather than measured week by week. That averaging is the part people miss. A 60-hour week in December is not automatically a breach if the surrounding weeks bring the 17-week average back under the cap.

A worker can sign an individual opt-out from the 48-hour limit. Three things about that opt-out are worth knowing before signing. It must be individual and in writing — a blanket clause buried in a staff handbook that nobody signed is on shaky ground. It can be withdrawn by giving notice, usually seven days unless the agreement specifies longer, up to a maximum of three months. And refusing to sign it is not a lawful reason to dismiss someone or to cut their hours in retaliation. Where the pressure to sign is informal — a supervisor saying the rota only works if everyone signs — the agreement is still legally an individual choice.

The opt-out covers the weekly hours cap only. It does not waive rest breaks, daily rest, weekly rest or paid holiday. Anyone told that signing it means they no longer get breaks has been told something untrue.

Night work is a separate regime

Someone who regularly works at least three hours during the night period — normally 11pm to 6am — counts as a night worker, and different rules apply. Night workers should not average more than eight hours in each 24-hour period across the reference period, and where the work involves special hazards or heavy physical or mental strain, that eight hours becomes an absolute limit rather than an average. Night workers are also entitled to a free health assessment before starting night work and at regular intervals afterwards. In practice most employers offer this as a short questionnaire; it is worth completing honestly rather than treating it as paperwork, because it is the mechanism by which someone who is medically unsuited to nights gets moved to day work.

How holiday accrues when the hours are irregular

The 5.6 weeks of statutory paid holiday is straightforward for someone on fixed days. It is much less obvious for agency, zero-hours, seasonal and part-year workers, which is precisely the population most likely to be underpaid.

For leave years beginning on or after 1 April 2024, holiday entitlement for irregular-hours and part-year workers accrues as a percentage of the hours actually worked in each pay period, calculated at 12.07 per cent. Employers of those workers are also permitted to pay holiday as an uplift on each payslip — “rolled-up” holiday pay — provided it is shown as a separate itemised line. Two failure modes follow from that. The first is an employer paying rolled-up holiday to a worker on fixed regular hours, where it is not permitted. The second is an employer claiming the hourly rate already includes holiday without any separate line on the payslip, which makes the claim unverifiable and usually means the rate is simply the rate.

Check the payslip for an explicit holiday line, and check that the base hourly figure has not been quietly reduced to fund it. If someone is on the minimum wage, the holiday uplift must sit on top of the minimum, not be carved out of it.

Sick pay: the mechanics matter more than the rate

Statutory Sick Pay is a weekly amount paid by the employer for qualifying days of sickness absence, up to a maximum of 28 weeks in a period of incapacity. The cash rate is uprated periodically and the current figure should always be read from the official government page rather than from a blog. What is more useful to understand is the machinery around it.

Historically SSP had two gates that excluded a large share of low-paid and part-time workers: a set of unpaid waiting days at the start of an absence, and a minimum weekly earnings threshold below which no SSP was payable at all. Reform legislated in 2025 is intended to remove both, so that sick pay starts from the first qualifying day and applies regardless of how low the earnings are. This is being brought in through commencement regulations rather than all at once, so anyone relying on it should check whether the change is in force for their own absence.

Two practical points survive whatever the rate is. Notify sickness exactly as the contract requires, in the stated way and within the stated window, because failure to notify is the most common lawful reason for refusing SSP. And self-certify for the first seven calendar days; a fit note from a healthcare professional is only needed from day eight onwards, so an employer demanding a doctor’s note on day two is imposing its own rule, not a legal one. If the employer refuses SSP it must explain why, in writing, on form SSP1 — and that form is what allows the worker to claim other support instead.

Occupational schemes sit on top, never underneath

Many employers run a contractual sick pay scheme that is more generous than SSP — full pay for a set number of weeks, then half pay, then SSP. Where that exists it is in the contract or the staff handbook, and it is enforceable like any other contractual term. Where it does not exist, SSP is the floor and nothing more. Someone comparing two job offers with similar hourly rates should read the sickness clause carefully, because the difference between four weeks of company sick pay and none is worth far more over a year than a small difference in the hourly figure.
