What is a zero-hours contract and what rights come with it?
A zero-hours contract is an arrangement with no guaranteed minimum hours. The employer offers work when available; how much obligation exists on either side depends on the contract's terms.
The two variants matter enormously:
Without mutuality — the employer need not offer work and you need not accept it. This is the more common form.
With an obligation to accept — you must take offered work but are guaranteed none. This is the more exploitative arrangement and is the version most criticised.
What rights you have. Zero-hours workers are almost always at minimum workers, and frequently employees depending on the reality of the arrangement. Either way you are entitled to:
National Minimum Wage for all hours worked, including some travel between assignments.
Paid holiday, accruing with hours worked. This is widely underpaid and worth checking — you are entitled to it regardless of irregular hours.
Rest breaks and working time protections.
Protection from discrimination and from unlawful deductions.
Whistleblowing protection.
Pension auto-enrolment if earnings qualify.
Statutory sick pay, if earnings reach the lower earnings limit.
Exclusivity clauses are banned. Since 2015 in the UK, a clause preventing a zero-hours worker from working elsewhere is unenforceable, and this was later extended to low-income workers on other contracts.
What you generally do not get unless you are an employee with sufficient continuous service: redundancy pay, statutory notice, and ordinary unfair dismissal protection. Continuity of employment is the difficult issue, since gaps between assignments can break it.
The practical problems are real and documented: income unpredictability making budgeting and renting difficult, difficulty obtaining credit or a mortgage, and the risk of zeroing down — being given no hours as an informal dismissal with no process.
Reform is ongoing, including proposals for a right to guaranteed hours reflecting actual worked patterns.
