What a zero-hours contract is and why it matters
A zero-hours contract is an arrangement under which the employer does not guarantee any minimum hours and offers work as and when it is available. The terms set out how work is offered, how it is accepted and what status the worker holds. Rules on this kind of arrangement vary widely between jurisdictions.
Its purpose is to provide flexibility where demand is irregular or hard to predict. For the employer it allows staffing to follow need; for the worker it can offer flexibility, but it makes clarity especially important — the agreement should explain whether hours are guaranteed, how offers work and what rights apply.
When a zero-hours contract is used
- For work where demand is irregular or hard to forecast.
- For event, hospitality, care or seasonal cover that fluctuates.
- For casual roles where workers value flexibility over guaranteed hours.
- To supplement a core team during unpredictable busy periods.
- Where local law permits this kind of flexible engagement.
What a clear zero-hours contract includes
- The names of the parties and the nature of the engagement.
- A clear statement that no minimum hours are guaranteed.
- How work is offered and how the worker accepts or declines it.
- The worker status under local law and the rights that follow from it.
- How pay is handled for hours actually worked, in line with local law.
- Any notice expected for cancelled or changed shifts.
- Whether the worker may take other work elsewhere.
- How leave and other applicable entitlements are calculated.
Common mistakes to avoid
- Implying that regular hours are guaranteed when they are not.
- Mislabelling the worker status and overlooking the rights that apply.
- Restricting the worker from other work where local law does not allow it.
- Failing to explain how shifts are offered and cancelled.
- Ignoring entitlements, such as leave, that still apply to the engagement.
- Using the arrangement to avoid obligations that local law still imposes.
Best practices
- Be transparent that no minimum hours are guaranteed.
- Check local law on worker status, exclusivity and applicable entitlements.
- Set out clearly how shifts are offered, accepted and cancelled.
- Treat workers fairly and consistently when offering available work.
- Export the signed agreement to PDF so the terms are fixed and easy to share.
