TL;DR: A zero-hours arrangement may suit genuinely variable or short-term demand, but it does not remove employment responsibilities. Workers retain statutory rights, and employment status depends on the reality of the relationship. The Employment Rights Act 2025 contains reforms on guaranteed hours, shift notice and short-notice changes; government guidance says the new measures are not yet in force and will change when the Act is fully implemented.
What a zero-hours contract usually means
The term commonly describes a casual arrangement where the employer does not guarantee work and the individual is not obliged to accept work offered. The label does not by itself decide whether someone is an employee, worker or genuinely self-employed. The working relationship matters.
When it may be appropriate
Current government guidance gives examples including a new business with uncertain demand, seasonal peaks, unexpected sickness cover and special events. It also says zero-hours contracts may not be suitable where work is regular and predictable over a continuous period; part-time, fixed-term, annualised-hours or agency arrangements may be more appropriate.
Rights and fair practice
- Provide the required written particulars and explain how work is offered.
- Give as much notice of shifts as possible and avoid last-minute cancellation.
- Remember applicable rights including National Minimum Wage, statutory annual leave, health and safety and protection from unlawful discrimination.
- Do not use prohibited exclusivity terms to prevent workers taking other work.
- Review whether actual working patterns indicate a different contractual arrangement is needed.
Prepare for further change
The Employment Rights Act 2025 provides for rights connected with guaranteed hours, reasonable notice of shifts and changes, and payments linked to short-notice cancellation or curtailment. Important implementation detail is being set through regulations. Employers should not present those future measures as already fully operational, but should prepare scheduling data, contract records and management processes now.
A sensible decision test
Before using a zero-hours arrangement, document why demand is genuinely uncertain, compare alternatives and assess the effect on recruitment, retention and service quality. Review the arrangement regularly with current legal advice.

A manager’s implementation checklist
Audit people described as casual, bank or zero-hours workers and compare the written contract with the actual pattern. Record hours offered, accepted, changed and cancelled so the business can understand operational practice and prepare for new requirements. Train scheduling managers to give reasonable notice, avoid retaliatory allocation decisions and escalate contract questions.
Forecast the genuinely predictable core of demand. Where a regular pattern has emerged, compare the cost and workforce impact of guaranteed part-time hours, annualised hours or a fixed-term arrangement. Consultation with affected workers can reveal availability and retention issues that a spreadsheet misses. Document the reason for the final choice and schedule another review.
