Zero Hours Contract Rights: What You Are Actually Entitled To

There is a persistent myth that a zero hours contract strips you of employment rights. It does not. Zero hours describes only one thing - that your employer is not obliged to guarantee you any minimum number of hours. It says nothing about your legal status or the rights that come with it. In reality, zero hours does not mean zero rights: everyone on this kind of contract is at least a worker, and some are employees, which unlocks an even longer list of protections set out in the Employment Rights Act 1996 and related legislation.

This guide explains what a zero hours contract actually is, the difference between worker and employee status and why it is the single most important question, the rights everyone has, the extra rights employees get, the ban on exclusivity clauses, and the reforms that are coming but are not yet law.

What is a zero hours contract?

A zero hours contract is an arrangement under which your employer does not guarantee any minimum hours of work. They offer shifts as and when work is available, and in many (though not all) cases you can decline shifts you are offered.

What a zero hours contract is not is a separate legal category that removes your rights. The label on the contract does not decide your status; the way the relationship actually works does. That is why two people on identically worded zero hours contracts can end up with different rights - one a worker, one an employee - depending on how the arrangement plays out in practice.

Worker or employee - why does it matter?

This is the load-bearing question for almost every zero hours dispute, because your rights depend on which category you fall into.

• A worker is someone who agrees to do work personally and is not genuinely running a business for a client. Workers get a solid core of rights.
• An employee works under a contract of employment, with mutual obligations - the employer to provide work and the individual to accept it - and gets the worker rights plus a significant set of extra protections.

The table below shows which rights attach to each status.

What rights does every zero hours worker have?

Because everyone on a zero hours contract is at least a worker, the following apply to all of them:

• National Minimum Wage / National Living Wage. Every hour you actually work must be paid at no less than the legal minimum for your age. Time spent on certain required activities can count too.
• 5.6 weeks paid holiday. All workers accrue paid annual leave. For irregular hours this is normally calculated at 12.07% of the hours worked. Holiday pay is one of the most commonly underpaid rights for zero hours staff - the full detail, including the 12.07% calculation and rolled-up holiday pay, is in our holiday pay entitlement guide.
• Rest breaks and working-time limits. Daily and weekly rest and limits on average weekly hours apply.
• Protection from unlawful deductions. Your employer cannot make unauthorised deductions from your wages.
• Whistleblowing protection. If you make a protected disclosure, you are protected from being penalised for it - see our guide to whistleblowing at work.
• Protection from discrimination. The Equality Act 2010 protects workers against discrimination, harassment and victimisation.

What extra rights do employees get?

If, on the facts, you are an employee rather than just a worker, you also gain:

• Unfair dismissal protection. This currently usually requires two years of continuous service. The government has targeted reducing that qualifying period to around six months from 1 January 2027, but as of mid-2026 that change is not yet in force - so treat the two-year rule as the current position and check the status before relying on a shorter period.
• Statutory redundancy pay, where the role disappears and you have the qualifying service. How that is calculated is covered in our redundancy pay guide.
• Statutory minimum notice of termination, the detail of which is owned by our notice periods guide.

How is status actually decided?

Because the contract label is not decisive, a tribunal looks at the reality of the relationship. The key factors include:

1. Mutuality of obligation - is the employer obliged to offer work and you obliged to accept it, at least when work is offered? A genuine, ongoing pattern of offering and accepting shifts can point towards employee status even on a "zero hours" label.
2. Personal service - must you do the work yourself, or can you send a substitute? A genuine, unfettered right to substitute usually points away from worker or employee status.
3. Control - how much does the employer direct how, when and where you work?

No single factor is conclusive, and tribunals weigh them together. A long, regular pattern of accepted shifts can, in similar situations, lead a tribunal to find that an employment relationship existed despite the zero hours wording.

Are exclusivity clauses enforceable?

No. A clause in a zero hours contract that prevents you from working for another employer - an exclusivity clause - has been unenforceable since 2015 under section 27A of the Employment Rights Act 1996.

In practice this means:

• You are free to take work from more than one employer.
• Any contractual term requiring your employer's consent before you work elsewhere is unenforceable.
• If you are dismissed or subjected to a detriment because you worked for someone else, you may have a claim.

This matters precisely because a zero hours contract gives you no guaranteed income - being able to combine work from several sources is often essential, and the law protects that.

What is changing under the Employment Rights Act 2025?

The Employment Rights Act 2025 is intended to bring substantial reform for zero hours and low-hours workers. The headline measures are expected to include:

• A right to be offered guaranteed hours that reflect the hours you have regularly worked over a reference period.
• A right to reasonable notice of shifts.
• A right to payment for shifts cancelled or curtailed at short notice.

These are significant changes, but a clear caution applies: as of mid-2026 these specific zero hours measures are not yet in force. They depend on commencement regulations and detailed rules still to be confirmed, and are widely expected to come into effect around 2027. Treat them as forthcoming, not current law, and check the up-to-date commencement position before relying on any of them.

What can I do if I have been underpaid?

Underpayment is the most common zero hours problem - unpaid holiday, hours paid below the minimum wage, or deductions you never agreed to. All of these can usually be pursued as an unlawful deduction from wages. The mechanics - the series rule, the two-year backstop, and how to calculate what you are owed - are set out in full in our guide to unpaid wages and unlawful deductions.

The time limit is tight: usually 3 months less 1 day from the last underpayment, and you must start ACAS Early Conciliation before issuing a tribunal claim. You can check a date with the free tribunal deadline calculator.

Key takeaway

Do not assume a zero hours contract leaves you with no protection. You are at least a worker, with the minimum wage, paid holiday, rest breaks and protection from deductions - and if the reality of your arrangement makes you an employee, you may have unfair dismissal, redundancy and notice rights too. The exclusivity ban frees you to work elsewhere, and bigger reforms are on the way, even if they are not yet law. If you think you have been underpaid or penalised, the first step is to check your real status against how you actually work.
