On a zero-hours contract? Understand your rights to holiday pay, minimum wage, and protection from exclusivity clauses under UK employment law.
Last reviewed: 30 March 2026
Quick answer
Workers on zero-hours contracts have more rights than many people realise. Under UK law, zero-hours workers are generally entitled to the National Minimum Wage, paid annual leave, rest breaks, and protection from discrimination. Exclusivity clauses in zero-hours contracts are unenforceable under the Small Business, Enterprise and Employment Act 2015.
What this means in practice
Zero-hours contracts mean there is no guaranteed minimum number of hours, and the worker is not obliged to accept work when offered. However, the employment status of the individual matters significantly — whether someone is classified as a worker or an employee affects their rights. Most people on zero-hours contracts are classified as workers, which entitles them to core protections including the National Minimum Wage, 5.6 weeks of paid annual leave, protection under the Equality Act 2010, and the right to be accompanied at disciplinary and grievance hearings. Some individuals on zero-hours contracts may in practice be employees, particularly if there is mutuality of obligation, which could entitle them to additional rights such as unfair dismissal protection and redundancy pay.
Common situations
Common situations include: being told there is no entitlement to holiday pay on a zero-hours contract, having hours cut after refusing a particular shift, being prevented from working for other employers through an exclusivity clause, not being paid the National Minimum Wage when accounting for all working time, being treated less favourably than permanent staff, and uncertainty about employment status and whether additional rights might apply.
What UK law says
Section 27A of the Employment Rights Act 1996 (inserted by the Small Business, Enterprise and Employment Act 2015) makes exclusivity clauses in zero-hours contracts unenforceable. The Working Time Regulations 1998 provide zero-hours workers with 5.6 weeks of annual leave (Regulations 13 and 13A). The National Minimum Wage Act 1998 applies to all workers. Section 230 of the ERA 1996 defines the distinction between employees and workers, which is critical for determining the full extent of rights. The Equality Act 2010 protects both employees and workers from discrimination. The Employment Rights (Employment Particulars and Paid Annual Leave) (Amendment) Regulations 2018 introduced the 52-week reference period for calculating holiday pay for irregular hours workers.
What people often consider
People on zero-hours contracts often consider whether their actual working pattern suggests they might have employee status rather than worker status, which would provide additional protections. Some explore whether reduced hours might amount to a detriment for exercising a statutory right. Others look into whether their holiday pay is being correctly calculated using the 52-week reference period. Those with exclusivity clauses in their contracts may want to be aware that such clauses are unenforceable. Seeking advice from Citizens Advice or ACAS may help clarify individual circumstances.
Common mistakes to avoid
Common mistakes include: assuming that zero-hours workers have no employment rights, not challenging exclusivity clauses that prevent working for other employers, not keeping personal records of hours worked and shifts offered or refused, accepting that holiday pay is not available on a zero-hours contract, and not checking whether actual working arrangements might indicate employee status rather than worker status.
Frequently asked questions
Can I refuse a shift on a zero-hours contract?
Generally, yes. A zero-hours contract typically means there is no obligation on the employer to offer work, and no obligation on the worker to accept it. However, it is worth checking the specific contract terms and being aware that in practice some employers may offer fewer shifts to workers who regularly refuse.
Can my employer stop me working for other companies?
No. Under s.27A of the Employment Rights Act 1996, exclusivity clauses in zero-hours contracts are unenforceable. This means an employer cannot prevent a zero-hours worker from working for other employers or subject them to a detriment for doing so.
How is holiday pay calculated on a zero-hours contract?
Holiday pay for zero-hours workers is typically calculated based on average weekly earnings over a 52-week reference period, excluding any weeks in which no pay was earned. This reference period was extended from 12 weeks to 52 weeks by the 2018 Amendment Regulations.
Am I an employee or a worker on a zero-hours contract?
This depends on the reality of the working relationship, not just the contract label. Factors that may indicate employee status include mutuality of obligation, regular working patterns, and integration into the business. Employment status affects which rights apply, so it may be worth seeking advice if there is uncertainty.
