Pregnancy and Maternity Discrimination: Your Rights at Work

Written by the Aricase editorial teamHow we write our guides

This guide covers England and Wales. It is general information, not legal advice, and is not a substitute for advice about your own situation. Laws and figures change - always check the current position on GOV.UK before relying on any detail here.

There are few moments more vulnerable than starting or expecting a family, and few that make unfair treatment at work sting more. Maybe your role or hours shifted the moment you shared the news, maybe a "restructure" appeared while you were on leave, or maybe you are quietly dreading going back at all. It is hard not to wonder whether you are being oversensitive at an emotional time. But pregnancy and maternity are among the most strongly protected things in UK employment law, from your very first day. This guide explains what counts as discrimination, the "protected period" around it, the special redundancy rules, and how a claim works.

Maternity discrimination is unlawful from your first day in the job. It has no qualifying period, and the compensation is not capped.

What is pregnancy and maternity discrimination?

Pregnancy and maternity discrimination means being treated unfavourably because of your pregnancy, because of an illness caused by your pregnancy, or because you are taking or have taken maternity leave. It is set out in section 18 of the Equality Act 2010.

There is an important difference between this and most other discrimination claims. For ordinary direct discrimination you usually have to show you were treated less favourably than someone else would have been - a comparator. For a section 18 pregnancy and maternity claim you do not. You only have to show the treatment was unfavourable and that it was because of pregnancy or maternity. That makes these claims, in principle, more straightforward to frame.

Examples of unfavourable treatment include being dismissed, demoted, denied training or a promotion, having your hours cut, being disciplined for pregnancy-related sickness absence, or being passed over in a redundancy exercise - where pregnancy or maternity is the reason.

The "protected period"

Section 18 protection applies during a defined window called the protected period. It begins when your pregnancy starts and ends:

  • when your maternity leave ends or you return to work, if you are entitled to maternity leave; or
  • two weeks after the end of the pregnancy, if you are not entitled to maternity leave.

Unfavourable treatment that happens during the protected period, and is because of the pregnancy or maternity, is what section 18 covers. Treatment after the protected period that is still connected to your pregnancy or maternity leave can often be brought as ordinary sex or other discrimination instead - the protection does not simply vanish, the legal label changes.

It is a day-one right

You do not need any minimum length of service. Pregnancy and maternity discrimination protection applies from your first day of employment - this is one of the genuine day-one rights, unlike ordinary unfair dismissal, which needs two years' continuous service where employment ends before 1 January 2027 (six months where it ends on or after that date).

Dismissal is protected twice over. As well as the Equality Act, section 99 of the Employment Rights Act 1996 makes a dismissal automatically unfair if the reason (or principal reason) is connected with pregnancy, childbirth, or maternity leave - again with no qualifying period.

Redundancy during pregnancy and maternity leave

A common misconception is that you cannot be made redundant while pregnant or on maternity leave. You can - but only through a genuine redundancy run fairly, and with extra protection layered on top.

During the protected period your employer must offer you any suitable alternative vacancy that exists, ahead of other employees who are also at risk. This is a priority right, not just a right to be considered. The Protection from Redundancy (Pregnancy and Family Leave) Act 2023, and the regulations that brought it into force in April 2024, extended this protected window: it now runs from the point you tell your employer you are pregnant through to 18 months after the birth.

If you are selected for redundancy because you are pregnant or on maternity leave, or you are not offered a suitable alternative role that existed, that is unlawful. For how statutory redundancy pay itself is worked out, see our redundancy pay guide.

What you can claim

If you bring a successful claim, an employment tribunal can award:

  • Loss of earnings - past and future, with no statutory cap (unlike the compensatory award for ordinary unfair dismissal)
  • Injury to feelings - a separate award for the upset and distress, assessed against the Vento bands, which run from lower-band awards for one-off incidents to higher-band awards for a sustained campaign
  • Interest on the awards

Because discrimination compensation is uncapped and includes injury to feelings, the value of a strong claim can be significantly higher than people expect.

How to bring a claim

The route is the same as other tribunal claims:

  1. Raise it internally first where you can - a grievance creates a record and may resolve things. See how to write a grievance letter.
  2. Start ACAS Early Conciliation - this is a mandatory step before you can lodge a tribunal claim.
  3. Lodge the ET1 within the time limit if conciliation does not resolve it.

Do not miss the deadline

The time limit is the part that catches people out. You generally have six months less one day from the act you are complaining about (three months less one day if it happened before 1 October 2026) - or from the last act, where there is a series of linked acts - to start ACAS Early Conciliation. Where the discrimination is ongoing, the clock may run from the most recent incident, but it is never safe to rely on that; treat the earliest possible date as your deadline. Full detail is in our tribunal deadlines guide.

In practice, missing the deadline almost always bars the claim, and tribunals only rarely extend time in discrimination cases where it is "just and equitable" to do so.

Key takeaway

If you have been treated unfavourably because of pregnancy or maternity, you are in one of the strongest-protected positions in employment law: protection from day one, no comparator needed, uncapped compensation, and priority redundancy rights. The thing that decides cases is preparation - a clear account of what happened, when, and the documents that show it, all filed before the deadline.

Frequently asked questions

Do I need two years' service to claim maternity discrimination?

No. Pregnancy and maternity discrimination under the Equality Act 2010 is a day-one right - there is no qualifying period. Dismissal for a pregnancy or maternity reason is also automatically unfair from day one under the Employment Rights Act 1996, so you do not need any qualifying service for that either.

Is there a cap on compensation for maternity discrimination?

No. Unlike the compensatory award for ordinary unfair dismissal, discrimination compensation under the Equality Act 2010 is uncapped. It can include loss of earnings and an injury-to-feelings award assessed against the Vento bands.

Can I be made redundant while pregnant or on maternity leave?

A genuine redundancy is still possible, but the process is tightly protected. During the protected period your employer must offer you any suitable alternative vacancy ahead of other at-risk colleagues. Following the Protection from Redundancy (Pregnancy and Family Leave) Act 2023, that priority now extends from when you tell your employer you are pregnant until 18 months after the birth. Selecting you because of pregnancy or maternity is unlawful.

Do I have to compare myself to another worker to show discrimination?

Not for a section 18 claim. You only need to show you were treated 'unfavourably' because of pregnancy or maternity - you do not need a comparator showing how someone else was treated, which is what direct discrimination under section 13 requires.

How long do I have to bring a claim?

Usually six months less one day from the act you are complaining about (or the last in a series of linked acts) where it happened on or after 1 October 2026, or three months less one day where it happened before, and you must start ACAS Early Conciliation first. Time limits are strict, so check your deadline early.
