A zero-hours contract can offer flexibility, but unpredictable shifts should not mean losing basic employment protections. If you work in hospitality, care or retail, you probably want clear answers about pay, holidays, hours and second jobs. Understanding zero hours contract rights in the UK begins with separating the absence of guaranteed work from the rights that still apply when you are working.
What does a zero-hours contract mean?
Usually, it means the organisation does not guarantee a minimum number of hours. Your income may rise or fall each week. It does not mean an employer can disregard minimum wage legislation, holiday entitlement or discrimination law.
Your legal status matters. Someone may be a worker, an employee or genuinely self-employed depending on the actual relationship, not merely the label printed on a contract. Workers generally receive core protections; employees may have additional rights, including certain dismissal protections. A useful starting point is understanding employment status and worker rights before assuming that “casual” means having no protections.
What are your pay rights?
Eligible workers must receive at least the applicable National Minimum Wage for working time. From April 2026, the rate is £12.71 an hour for people aged 21 and over, £10.85 for ages 18 to 20, and £8 for eligible younger workers and apprentices qualifying for that rate. Your contract may promise more.
Check your payslip against hours actually worked. Required training, preparation before opening and some travel between jobs can count towards minimum wage working time. An ordinary commute generally does not.
Imagine a café asks you to arrive 20 minutes before each scheduled shift to prepare the counter, but records only the published rota hours. Keeping your own start times gives you evidence if those additional duties mean you were underpaid. Guidance on checking minimum wage underpayments can help with the next calculation.
Are cancelled shifts paid?
Under the current general rules, payment for a shift cancelled before work begins is not automatic. Your contract or another applicable agreement may provide compensation. Work already performed must still be paid appropriately. Separate, stronger statutory cancellation protections are planned but are not yet generally in force.
Zero hours holiday pay and entitlement
Zero-hours workers generally have statutory paid annual leave. The minimum entitlement is 5.6 weeks a year, subject to the relevant rules and the usual 28-day cap. Variable schedules make calculations less familiar, but being called a casual worker does not cancel the entitlement.
For qualifying irregular-hours and part-year workers in Great Britain, leave years starting on or after 1 April 2024 use an accrual method based on 12.07% of hours worked in each pay period, up to the statutory maximum. Not every worker on a zero-hours contract necessarily satisfies the legal definition of irregular-hours working.
For example, 50 hours worked in a pay period generates about 6.04 hours of leave, rounded to six hours under the applicable rule. That represents paid time off, not an extra shift.
Employers can use separately identified rolled-up holiday pay for eligible irregular-hours and part-year workers. Otherwise, holiday pay when leave is taken is generally based on the appropriate reference-period calculation. Leave entitlement and how it is paid are different issues. Understanding holiday pay for variable hours can help you review a confusing payslip.
Northern Ireland has separate holiday legislation. Check the rules where you work rather than assuming the Great Britain calculation applies unchanged.
Can you turn down shifts or request steadier hours?
Many zero-hours arrangements allow workers to decline offered shifts, but the exact obligations depend on your agreement. Do not assume every flexible contract is identical. Once you accept a shift, you may have contractual duties to attend.
Working-time protections still matter. For example, a worker ordinarily has a right to a 20-minute uninterrupted rest break when working more than six hours, although exceptions can apply. Rules on daily rest and average weekly hours may also be relevant.
If you have worked similar hours for months, save the rotas. The pattern may help when requesting a different contract or assessing your true employment status, though regular shifts alone do not automatically make you an employee.
Exclusivity clauses and second jobs
An exclusivity clause tries to prevent other employment or requires permission to accept it. Such clauses are unenforceable in zero-hours contracts. Similar protection extends to certain workers on contracts with earnings at or below the relevant lower earnings limit.
In practice, an employer generally cannot keep you on an unpredictable rota while prohibiting you from earning income elsewhere. You must still respect lawful confidentiality, health-and-safety obligations and commitments for shifts you have accepted.
Sick pay and other casual worker rights
Workers have protections against unlawful discrimination and rights including statutory holiday and minimum wage. Employees can qualify for further rights relating to family leave and dismissal, subject to applicable conditions.
Statutory Sick Pay is not automatic for everyone described as a worker: statutory eligibility rules apply. Since 6 April 2026, eligible employees can receive it from the first full qualifying day of sickness, without the former lower earnings threshold. The weekly rate is the lower of £123.25 or 80% of normal weekly earnings.
Which zero-hours reforms apply in 2026?
The Employment Rights Act 2025 sets out further protections involving offers of guaranteed hours, reasonable notice of shifts and payments for shifts cancelled, moved or shortened at short notice. As of October 2026, these main new measures are not yet generally in force. Implementation and detailed rules remain important.
Distinguish an existing legal right from a reform that has been announced but not commenced. The principal new zero-hours provisions concern Great Britain, while Northern Ireland has a distinct employment-law framework.
What to do when your rights are ignored
Keep your contract, rotas, messages about cancellations, actual hours, holiday records and payslips. Ask payroll in writing about any discrepancy and retain the response. Evidence is particularly valuable when schedules change every week.

Frequently asked questions
Do zero-hours workers get holiday pay?
Yes, eligible workers have statutory paid holiday rights. How leave and pay are calculated depends on their working pattern and applicable national rules.
Can an employer stop offering me work?
A genuine zero-hours contract ordinarily makes no promise of future shifts. However, withholding work for a discriminatory or otherwise unlawful reason may still be challenged.
Can I have two zero-hours jobs?
Generally, yes. An unenforceable exclusivity term cannot prevent you taking another job. Avoid clashing accepted shifts and respect lawful safety obligations.
Do regular shifts make me a permanent employee?
Not automatically. A steady pattern may be relevant evidence, but employment status depends on the whole relationship and its actual obligations.
Protect your rights while working flexibly
Zero hours means no guaranteed volume of work, not no protection. Check your real employment status, track paid hours, understand leave accrual and question restrictions on second jobs. Keep an eye on the commencement of new reforms, but base any immediate complaint on rights already in force.
