Zero-Hours Contracts: What You're Actually Entitled To

The phrase "zero-hours contract" has become a catch-all for anything that sounds precarious. But the legal reality is more nuanced - and more protective - than most workers on these contracts realise.

If you're working flexible or on-call shifts, here's what you're actually entitled to under UK law.

You still have employment rights from day one

Regardless of how many hours you work, you have basic employment rights the moment you start working for someone:

• National Minimum Wage - you must be paid at least the NMW for every hour you work, including time spent waiting to be called on shift if you're required to be present.
• Holiday pay - you accrue paid holiday entitlement proportionally. The legal minimum is 5.6 weeks per year (pro-rated to hours worked).
• Rest breaks - you're entitled to an unpaid 20-minute break if you work more than 6 hours in a shift.
• Protection from unlawful wage deductions - your employer cannot deduct pay for things like uniform costs or training if it would bring your hourly rate below the NMW.

Holiday pay is where most workers lose out

Holiday pay on variable hours is frequently underpaid - sometimes accidentally, sometimes not.

Since April 2020, holiday pay must be calculated using your average pay over the previous 52 weeks (excluding weeks where you earned nothing). If your pay varies due to shift bonuses, overtime, or irregular hours, all of that variation should feed into the calculation.

If your employer is just paying your base hourly rate and ignoring overtime or premium shifts in the holiday pay calculation, they're likely underpaying you.

You cannot be penalised for turning down shifts

This is one of the most misunderstood aspects of zero-hours work. Your employer cannot legally treat you unfavourably for turning down a shift you were offered. That includes reducing future offers, changing your rota position, or terminating your contract.

In practice this can be hard to prove, but it is unlawful. If you notice a pattern - you said no to a shift and suddenly your hours dropped significantly - that's worth documenting.

Exclusivity clauses were banned in 2015

An employer on a zero-hours contract cannot legally stop you from working for other employers. Exclusivity clauses - clauses that require you to be available exclusively for one employer while not guaranteeing hours - have been unenforceable since May 2015.

If your contract still contains one, it cannot be enforced. You are free to take on other work.

The 12-week rule and continuous employment

If you work regularly for the same employer, even on a zero-hours basis, you may be building up continuous employment. After two years of continuous employment, you gain additional rights including protection from unfair dismissal.

Courts look at the reality of your working arrangement, not just what the contract says. Working every week for two years, even if hours vary, can establish continuity.

Statutory Sick Pay - often overlooked

If you earn above the lower earnings limit (currently £123/week) on average, you're entitled to Statutory Sick Pay (SSP) when you're ill. It doesn't matter that your hours fluctuate week to week - what matters is whether your average weekly earnings clear that threshold.

If you're close to the threshold it's worth knowing your average. A simple way to check: add up your last eight weeks of gross pay, divide by eight. If it's over £123, SSP applies to you.

What "worker" status actually means

Most zero-hours staff are classified as workers rather than employees. Workers get slightly fewer rights than employees (no unfair dismissal protection until two years, for example), but they still receive:

• NMW
• Holiday pay
• Working Time Regulations protections
• Auto-enrolment pension contributions (if earnings are high enough)
• Whistleblower protections

If your employer is treating you as self-employed but you follow their schedules, use their equipment, and can't send a substitute - you may legally be a worker or employee. Employment status is determined by reality, not paperwork.

Keep records. They matter more than you think.

If you ever need to dispute holiday pay, claim SSP, or raise a grievance, the single most useful thing you can have is a record of your hours worked, shifts taken, and pay received.

Your employer is required to keep payslips, but having your own log that doesn't depend on them is valuable insurance.

Knowing your rights is only useful if you can evidence your situation. A few minutes logging each shift is a small habit with a potentially large payoff.
