Part-time worker rights: pay, holiday and pensions

Three days a week should mean a smaller payslip, not a cheaper hourly rate or a missing pension contribution. If your pay, holiday or benefits look wrong, save this week’s rota and payslip, then compare them with a full-time colleague’s terms. Write to your manager or payroll today. A deadline may already be running.

Who counts as part-time?

There is no legal threshold of 35, 30 or 16 hours. The test is your employer’s custom and practice for workers on the same type of contract. You must be paid wholly or partly by reference to time worked. The Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 have protected part-time workers in Great Britain since 1 July 2000. Northern Ireland has equivalent regulations.

The protection covers employees and other people with worker status, including many casual and zero-hours staff. Genuinely self-employed people are outside it. Holiday and minimum wage rights also cover workers, but unfair dismissal, statutory redundancy pay and statutory family leave generally require employee status. Sick pay has its own eligibility test. Our guide to employee, worker and self-employed status explains the distinction.

Find the right full-time comparator

You normally need a full-time worker employed by the same employer, under the same type of contract, doing the same or broadly similar work. Relevant qualifications, skills and experience count. Look at your own workplace first; you can use another establishment if no suitable comparator works at yours.

Under the amended regulations, ordinary employees, apprentices and non-employee workers are separate contract categories. A fixed-term contract is not automatically a different type from a permanent one. If you work through an agency, identify who employs or engages you before choosing a comparator. A hirer’s employee is not automatically your comparator; agency-worker rights provide a separate route.

The default is pro rata, which means in proportion to your hours. If you work half the full-time hours, half an equivalent annual bonus may be fair. A lower hourly rate is different: the rate already measures pay per hour. The regulations require pro-rating unless it is inappropriate for the benefit being compared.

Pay: same hourly rate, pro-rata extras

If your comparable full-time colleague earns £14 an hour, your starting point is £14 an hour too. A lower rate because you work fewer days needs objective justification. The minimum wage floor applies regardless of part-time status. From 1 April 2026, the adult rate for workers aged 21 and over is £12.71 an hour. That makes the minimum gross pay for a 15-hour week £190.65. See minimum wage rates and rights for younger workers and apprentices.

Compare each benefit on its own terms. A £500 annual bonus based on contracted hours for a 37-hour week would normally become £250 for an 18.5-hour week. A shift allowance linked to particular shifts should reflect the shifts you actually work, not simply be halved. Excluding all part-timers from a bonus or pay rise needs objective justification.

Extra hours and overtime premiums are different

Check your contract for payment for extra hours. There is no general statutory right to an overtime premium, and some contracts include unpaid overtime, subject to minimum wage rules. Where your contract pays extra hours at your hourly rate, working beyond your part-time hours does not make those hours free.

Under regulation 5(4), an employer can normally make you reach the comparable full-timer’s normal hours before paying the same enhanced overtime rate. Your contract may be more generous. See overtime pay rules.

Holiday: 5.6 weeks, scaled to what you work

For regular, year-round work, your statutory minimum is 5.6 of your own working weeks, subject to the 28-day cap. Three days a week gives you 3 × 5.6 = 16.8 days. Those are days you would otherwise work, not calendar days.

Hours can make the calculation clearer. Three seven-hour days give you 117.6 hours of annual leave. Spread the same 21 weekly hours over five short days and you still get 117.6 hours, but each day’s leave uses fewer hours. If comparable full-timers receive more than the statutory minimum, you should normally receive a proportionate share of that extra leave too.

Bank holidays depend on the contract

There is no separate statutory right to paid bank holidays. Your employer can count them within your 5.6 weeks. The number of bank holidays differs across the UK, so do not assume every workplace uses eight.

If a full-time contract provides a separate allowance for eight bank holidays, a worker doing three equal-length days out of five would normally receive 8 × 3 ÷ 5 = 4.8 equivalent days. A holiday pot in hours can avoid unfairness between Monday and non-Monday workers. Deduct only the hours you would have worked when a bank holiday falls on your working day. A bank holiday on a day you never work should not use up your statutory leave.

Irregular hours and part-year work

In Great Britain, for leave years starting on or after 1 April 2024, qualifying irregular-hours and part-year workers accrue statutory holiday at 12.07% of hours worked each pay period. A rotating shift pattern with fixed contracted hours is not automatically irregular-hours work. These are specific legal categories, not labels for everyone working part-time.

For example, 70 hours worked in a monthly pay period gives 70 × 12.07% = 8.449 hours before rounding. Under the statutory rounding rule, that becomes 8 hours, because the fraction is less than half an hour. Fractions of half an hour or more round up. Holiday also accrues during sickness and statutory family leave under separate calculations.

Employers can choose rolled-up holiday pay for these workers only. This is an extra payment, normally 12.07% of total pay, shown separately on each payslip. You still have the right to take leave. It changes when holiday pay arrives, not whether you get time off. Do not apply these GB reforms to Northern Ireland without checking its separate rules. The government’s holiday reform guidance explains the calculations.

What should a week’s holiday pay include?

For a regular GB worker, at least four weeks of statutory leave must be paid at normal remuneration, which can include regular overtime, commission and relevant bonuses. The remaining 1.6 weeks can be paid at basic pay. If you earn £294 basic pay plus £30 of regular overtime a week, a week’s leave from the four-week pot should reflect £324, assuming those figures represent your normal pay. Variable pay can require averaging. Our holiday pay guide covers the detail.

Pensions: the £10,000 per-job trap

Working part-time does not allow an employer to exclude you from its pension simply because of your hours. But automatic enrolment has an earnings test for each job separately. You normally qualify if you are aged at least 22 but below State Pension age, ordinarily work in the UK and meet the £10,000 annual earnings trigger. Two jobs paying £7,000 each do not combine to trigger enrolment.

The 2026/27 thresholds are £10,000 for automatic enrolment and £6,240 to £50,270 for qualifying earnings. In a scheme using that band, minimum contributions are 8% in total, with at least 3% from the employer. A scheme can use a different compliant contribution basis or offer more.

If you are aged 16 to 74 and earn more than £6,240 but do not qualify for automatic enrolment, you can normally opt in and receive employer contributions. At £6,240 or less, you can ask to join a pension, but the employer does not have to contribute. These annual figures have pay-period equivalents, so a bonus or extra shifts can affect the assessment. See GOV.UK’s joining rules and our workplace pension guide.

Sick pay and family leave: what changed in April 2026

Since 6 April 2026, Statutory Sick Pay is the lower of £123.25 a week or 80% of average weekly earnings, for up to 28 weeks. The earnings floor and three waiting days have gone. Eligible staff receive SSP from the first full qualifying day of sickness. It is paid for qualifying days, normally the days you would work, not every calendar day.

At average weekly earnings of £110, a full qualifying week’s SSP is 80% × £110 = £88. Before the reform, those earnings were below the eligibility floor. Being a “worker” for holiday purposes does not automatically qualify you for SSP; check the separate SSP eligibility rules. Contractual sick pay may be higher, and must respect part-time equal-treatment rights. See our sick pay guide.

Statutory family leave does not get shorter because you work fewer days. If you qualify for maternity leave, for example, its duration is the same for a two-day worker as a five-day worker. Leave and pay have separate eligibility rules, including service and earnings conditions where applicable.

For 2026/27, Statutory Maternity Pay is 90% of average weekly earnings for six weeks, then the lower of £194.32 or 90% for up to 33 weeks. Someone with £200 average weekly earnings receives £180 a week in both periods. SMP still requires average earnings of at least £129 a week and the relevant service conditions. Removing the SSP earnings floor did not remove it for maternity pay.

In Great Britain, paternity leave and unpaid parental leave became day-one employee rights on 6 April 2026. That did not make statutory paternity pay a day-one right. See maternity leave and pay, paternity leave and pay and shared parental leave for each scheme’s conditions.

Training, promotion, redundancy and dismissal

“You’re only part-time” is not a reason to leave you out of training or promotion. Equal access does not mean every arrangement must be identical, but an employer needs objective grounds for a disadvantage caused by part-time status. Ask for the actual reason. A course timetable or a manager’s preference for full-time staff is not, by itself, proof that exclusion is justified.

The same principle applies to transfers, career breaks and other employee benefits. A business reason must explain why the particular difference is necessary and appropriate. An employer cannot make an exclusion lawful just by calling it company policy.

Part-time years count in full for redundancy

Statutory redundancy pay requires employee status and at least two years’ continuous service. Working half the hours does not halve your service. The age multipliers are the same: half a week’s pay for each full year below age 22, one week for each full year aged 22 to 40, and one-and-a-half weeks for each full year aged 41 or over. Up to 20 years count, using your relevant weekly pay.

From 6 April 2026, Great Britain’s statutory week’s-pay cap is £751, making the maximum £22,530. Northern Ireland’s cap is £783. The statutory redundancy rules and our redundancy pay guide explain the calculation.

An employer must not select you for redundancy simply because you work part-time without objective justification. You can also challenge dismissal for asserting rights under the part-time regulations. For employees, that can be automatically unfair without a qualifying service period under regulation 7.

As at 1 October 2026, ordinary unfair dismissal in Great Britain generally requires two years’ service. Service is measured in time, not hours: three years at 16 hours a week counts as three years.

If you are treated worse: what to do

After a long shift, keep it simple: save your contract, the latest payslip and rota, then note the full-time colleague whose terms you are comparing. Write down the difference and the date it happened. If training or promotion was denied, save the advert and rejection. A manager saying “part-time staff aren’t eligible” is not the end of the matter.

1. Ask for written reasons. If you believe the part-time regulations have been breached, write to your employer requesting reasons for the treatment. They must give you a written statement within 21 days under regulation 6.
2. Raise a grievance and get support. Set out the term or decision you challenge, your comparator and the remedy you want. A union representative or adviser can help assess the employer’s justification.
3. Contact the conciliation body before the deadline. In Great Britain, notify Acas for early conciliation; in Northern Ireland, contact the Labour Relations Agency. A grievance or request for reasons does not stop the tribunal clock. The statutory early-conciliation rules can adjust it.
4. Calculate the correct claim deadline. For a GB part-time-regulations complaint whose relevant date is on or after 1 October 2026, the ordinary limit is six months less one day. Earlier relevant dates generally retain the old three-month limit. Northern Ireland generally retains three months less one day. Get advice promptly rather than waiting for a reply.

You do not have to tackle this alone. Contact your union representative; UNISON, Unite and GMB organise workers in health and care, hospitality, retail, warehouses, delivery and cleaning. Citizens Advice and local law centres can help if you are not a member. Report underpayment of the minimum wage to HMRC. Report labour exploitation to the GLAA, unsafe work to the HSE, and discrimination to the Equality and Human Rights Commission. A report does not replace a tribunal claim or extend its deadline.

The transition is set out in SI 2026/758, regulations 3 and 10. The relevant date is the treatment or detriment complained of, or the last act in a qualifying series. A continuing contractual term has specific rules. For a single qualifying act on 1 October 2026, the unadjusted six-month deadline is 31 March 2027. Early conciliation can change the final date; do not simply add its duration yourself. See bringing a tribunal claim.

If your employer withholds reasons unreasonably or answers evasively, a tribunal may draw an adverse inference. Under regulation 8, remedies include a declaration, compensation for financial loss and a recommendation to remedy the disadvantage. Compensation for less favourable treatment under regulation 5 does not include injury to feelings. A separate discrimination claim may allow it.

Scotland and Northern Ireland

Scotland follows the same part-time regulations as England and Wales. The October 2026 extension for these claims applies across Great Britain. The later change for Scottish breach-of-contract tribunal claims does not delay a Scottish part-time-regulations complaint.

Northern Ireland uses the Part-time Workers Regulations (Northern Ireland) 2000. Claims go to industrial tribunals, with Labour Relations Agency early conciliation. The GB six-month extension does not apply. Ordinary unfair dismissal generally requires one year’s service, and statutory flexible-working requests generally require 26 weeks. The redundancy week’s-pay cap is £783 from 6 April 2026.

Minimum wage rates, pension automatic-enrolment thresholds and the April 2026 SSP reforms apply in Northern Ireland too. Do not assume the GB day-one paternity and unpaid parental leave changes or its irregular-hours holiday reforms apply there. Our Northern Ireland employment guide explains the separate rules.

What changes next

The Employment Rights Act 2025 has further changes scheduled. Under the government’s timetable updated on 25 September 2026, Great Britain’s ordinary unfair dismissal qualifying period is scheduled to fall to six months for dismissals from 1 January 2027. Future dates remain subject to parliamentary processes and may change.

Questions people ask

How many hours a week count as part-time?

There is no universal statutory number. The regulations look at your employer’s custom and practice for workers on the same type of contract. A 35-hour threshold is a convention, not the legal test.

Can your employer pay you a lower hourly rate?

Not simply because you work part-time. Compare with a full-timer at the same employer doing the same or broadly similar work under the same type of contract. A difference caused by part-time status needs objective justification; differences in relevant skills or experience may affect the comparison.

Do you get paid for extra hours?

Your contract determines payment for additional hours, subject to minimum wage rules. There is no general statutory overtime premium. The part-time regulations normally allow an employer to wait until you exceed comparable full-time hours before paying an enhanced rate, unless your contract provides more.

Do you get bank holidays if you never work Mondays?

You have no separate statutory entitlement to bank holidays, but you still need your full paid holiday allowance. A contractual bank-holiday benefit must also respect part-time equal treatment. Ask how the employer calculates your share; it should not deduct statutory leave for a day you were never due to work.

Can you get employer pension contributions from two small jobs?

Yes, if you meet the opt-in conditions in each. Two steady £7,000 jobs do not trigger automatic enrolment, but a worker aged 16 to 74 can normally opt in at each and receive employer contributions. Your combined annual earnings are not the enrolment test.

How long do you have to challenge less favourable treatment?

For GB part-time-regulations claims with a relevant date on or after 1 October 2026, normally six months less one day before early-conciliation adjustments. Earlier claims generally retain three months; Northern Ireland normally has three months less one day. Ask for advice immediately if dates, a continuing term or a series of decisions are involved.
