What are zero hours contracts and who uses them?

Zero hours contracts are flexible agreements where an employer does not guarantee any hours, but workers can be called in when needed. They’re common in hospitality, retail, care, and some gig platforms.

A zero hours contract is a working arrangement in which you are not promised a set number of hours. Instead, shifts are offered as and when the employer requires you to work. You may be contacted the same day or a few days in advance, and you’re paid for the hours you actually work.

These contracts are popular in industries with fluctuating demand—such as hospitality, supermarkets, care services, and certain online platforms. They can give employers flexibility while offering workers the chance to fit work around other commitments. However, for the worker, there is often less certainty about weekly income.

Importantly, even if you have a zero hours contract, you still accumulate rights and protections when you work. Your pay, holiday entitlement, and other minimum protections apply to the hours you are contracted to perform or actually perform, depending on the rule.

• No guaranteed hours; shifts are offered as needed
• Paid for hours actually worked, not a fixed salary
• Common in hospitality, retail, care, and some platform work
• Can offer flexibility but bring income uncertainty
• Rights like minimum wage and holiday pay still apply when you work

What is your employment status and why does it matter?

Status determines which rights you have. Most zero hours workers are 'workers' rather than 'employees', which affects holiday pay, minimum wage, and the ability to bring certain claims.

In UK law, your status is not just a label—it decides which rights apply to you. The main categories are employee, worker, and the self-employed. A person on a zero hours contract is often a 'worker' rather than an 'employee', but it depends on the level of obligation and control present in the contract.

Key tests look at whether your employer is obliged to offer work (mutuality of obligation) and how much control the employer has over your work. If there is a high degree of commitment from the employer to provide work, you may be more likely to be an employee. If you mainly bring your own availability and the employer’s obligation is limited, you may be a 'worker'.

Your status affects rights such as paid holiday, minimum wage, and protection against unlawful deductions or unfair dismissal. If your status changes, it can unlock additional protections or alter your entitlements.

• Employee: broad, ongoing rights; written contract often includes mutual obligations
• Worker: limited rights; right to minimum wage, holiday pay, and certain protections
• Self-employed: different regime; usually not entitled to the same rights as workers
• Key tests: mutuality of obligation and degree of control
• Status can influence eligibility for tribunal remedies and compensation

Your rights as a zero hours worker

Even with no fixed hours, you still have core protections, including minimum wage, holiday pay, and rest breaks. The exact amounts depend on hours worked and your age.

You are entitled to be paid at least the National Minimum Wage or National Living Wage for the hours you actually work. This is a core entitlement independent of your hours’ uncertainty.

Holiday pay accrues as you work. Workers and employees are entitled to a minimum of 5.6 weeks’ paid holiday per year, pro-rated if you work part-time. The way holiday is calculated can depend on how hours are counted, so keep a clear record of shifts.

Rest breaks and maximum working time are governed by the Working Time Regulations. If you work long shifts, you’re legally entitled to break periods and reasonable rest. In practice, many zero hours workers assert their right to breaks as part of the day’s schedule.

Other protections include protection against unlawful deductions from wages and access to complaint mechanisms or disputes resolution. If you are treated differently from others for the same work, you may have a claim for discrimination or a breach of the equality framework (if applicable).

• Minimum wage rights apply to hours worked
• Holiday pay accrual regardless of fixed hours
• Rest breaks and limits on working time
• Protection from unlawful deductions and unfair treatment

How to challenge a zero hours contract or push for fixed hours

If you want more predictable hours, start with a conversation, collect evidence, and use formal channels if needed. You can seek ACAS guidance and, if required, Employment Tribunal relief.

If you’re uncomfortable with your current arrangement, begin by raising the issue with your employer. Bring clear records of shifts offered, hours worked, and any discrepancies in pay.

Ask for a written contract outlining hours, terms, and expectations. A written agreement can help protect both sides and prevent misunderstandings.

If informal discussions don’t resolve the issue, consider formal channels. ACAS offers free early conciliation to help resolve disputes without going to tribunal. You can also use a written grievance and your statutory rights as leverage.

If all else fails, you may pursue a claim at an Employment Tribunal. Time limits apply, typically three months from the act or failure to act that you challenge; extensions may apply if reasonably practicable to extend the period or for mediation-related extensions.

• Ask for written terms and hours
• Keep records of offers and hours
• Use ACAS early conciliation
• File a tribunal claim within time limits if needed
• Consider tribunal routes if there is a breach of rights

1. Step 1: Document all offers and hours
2. Step 2: Request written terms
3. Step 3: Seek ACAS early conciliation
4. Step 4: If unresolved, pursue tribunal with evidence

Gig workers and agency workers: where protections differ

Gig workers often operate through agencies or platforms. Rights depend on status, and agency worker protections can apply after a qualifying period, with specific pay protections in some cases.

Gig workers may be classified as workers or self-employed depending on the contract and control. Agency workers are supplied to hirers and often have additional protections, including access to equal pay and certain protections after a set period of work.

The law provides that agency workers should be paid for the work performed and can have rights equivalent to those of directly employed workers after a qualifying period (though the exact entitlements can vary by sector).

Platform-based workers should check whether their arrangement is covered by worker rights or whether there are particular exemptions or protections that apply to the platform they work through.

• Worker status affects rights
• Agency workers may gain equal pay and specific protections
• Platform workers should check terms and coverage
• Rights may advance after a qualifying period
• Always pursue proper pay for work done

Claim process and time limits: what to know before you act

Time limits for tribunal claims are usually three months from the act or failure to act, but extensions are possible for practical reasons or mediation contexts.

The standard time limit for most Employment Tribunal claims is three months minus a day from the act or omission you’re challenging. This deadline is important and begins from the date of the incident, not when you realise there is a problem.

Tribunals can extend the time limit in certain circumstances if it was not reasonably practicable to comply, such as when there has been mediation or delays caused by late receipt of documents. It is important to act promptly and seek advice early.

For agency workers, the same general framework applies, though some schemes have their own timelines and complaint routes. If you miss the deadline, you can apply for an extension, but you’ll need to show it was just and practicable to do so.

• Three months minus a day is the usual limit
• Tribunals can extend time in justified cases
• Act promptly and keep records
• ACAS can help with early conciliation
• Know the specific route for agency workers if applicable

1. Step 1: Identify the act or omission you want to challenge
2. Step 2: Gather evidence and timelines
3. Step 3: Contact ACAS for early conciliation
4. Step 4: Submit tribunal claim within time limits if needed

Conclusion

FAQ

Common questions about zero hours contracts rights answered in plain English.

What is the difference between a worker and an employee in the UK?

A worker has fewer rights than an employee, but still has key protections; employees have more extensive rights and duties.

In UK law, the difference centres on the level of obligation and control. Employees usually have ongoing contracts, mutual obligation to provide and accept work, and greater rights. Workers have more limited rights, including minimum wage, holiday pay, and protection from unlawful deductions. The exact status depends on the contract and the practical reality of the work relationship.

• Employees: more rights, stronger protections
• Workers: fewer rights but still protected
• Status tests focus on obligation and control

Do zero hours contracts guarantee minimum wage?

Yes — when you work, you are entitled to at least the minimum wage; the hours you work determine the pay.

Yes. When you work, you must be paid at least the National Minimum Wage or National Living Wage. Your pay should reflect the hours you actually work, whether those hours are fixed or variable.

• Minimum wage applies to hours worked
• Employers must track time accurately
• Disputes can arise over what counts as working time
