Part-time worker rights — equal pay, benefits and protection from unfair treatment

The Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000 are frequently breached and rarely enforced — because most part-time workers don't know they have these rights. If you are being treated worse than a comparable full-time colleague without a proper reason, you can bring a claim.

Part-time worker? You have the same rights as full-time colleagues, pro-rata

Know your part-time rights

Do part-time workers have the same rights as full-time workers?

Yes, on a pro-rata basis. The Part-Time Workers (Prevention of Less Favourable Treatment) Regulations 2000 give part-time workers the right not to be treated less favourably than a comparable full-time worker, unless the treatment can be objectively justified.

What counts as less favourable treatment for part-time workers?

Less favourable treatment includes: lower hourly pay, exclusion from bonus schemes, fewer holidays (pro-rata), denial of pension membership, less access to training, and exclusion from career progression opportunities — all without objective justification.

Can I be selected for redundancy because I work part-time?

Selecting someone for redundancy because they work part-time is a form of less favourable treatment under the Part-Time Workers Regulations. It may also constitute indirect sex discrimination (since women are more likely to work part-time), which carries no compensation cap.

Who is a comparable full-time worker?

A comparable full-time worker is someone employed by the same employer, under the same type of contract, engaged in the same or broadly similar work, and based at the same establishment (or a different establishment where common terms and conditions apply).

What is the time limit to claim less favourable treatment as a part-time worker?

3 months less one day from the date of the act complained of. ACAS Early Conciliation must be started before filing at the Employment Tribunal.

What equal treatment means for part-time workers

Your hourly rate must be the same as a comparable full-time worker. You cannot be paid a lower rate simply because you work fewer hours. Overtime rates: you should receive the same overtime premium as full-timers, but only once you have exceeded the standard full-time hours — not from your first extra hour.

You are entitled to 5.6 weeks' holiday pro-rated to your hours. So a 3-day-per-week worker is entitled to 16.8 days. You cannot be given fewer holidays per hour worked than full-time colleagues.

Access to any bonus or incentive scheme cannot be denied to part-time workers without objective justification. The amount should be pro-rated to hours worked.

Occupational pension

You cannot be excluded from your employer's pension scheme simply because you work part-time. Auto-enrolment thresholds apply equally, and if a full-timer would be in the scheme at your earnings level you should be too.

Training and promotion

Part-time workers must have equal access to training and career development. Blocking promotion on the grounds that a role "cannot be done part-time" may be indirect sex discrimination if the practice cannot be objectively justified.

Health insurance, childcare vouchers, gym membership, and similar benefits must be available to part-time workers on equal or pro-rata terms.

The link to sex discrimination

Treating part-time workers less favourably often amounts to

indirect sex discrimination

because women are statistically more likely to work part-time (due to caring responsibilities). If a policy disadvantages part-time workers and cannot be objectively justified, it is indirectly discriminatory.

The importance: sex discrimination claims have

. A claim under the Part-Time Workers Regulations on its own is subject to the unfair dismissal cap, but running a discrimination claim alongside significantly increases the potential award and includes injury to feelings.

Requesting a written statement of reasons

If you think you are being treated less favourably, you can ask your employer in writing for a written statement explaining the reasons for the treatment. They must respond within 21 days. An inadequate or evasive response can be used as evidence in tribunal proceedings.
