Pregnancy should not turn a promising career into a series of closed doors. Yet unfair treatment can begin with a manager’s reaction to an announcement, continue through maternity leave and become particularly visible when someone returns to work. Understanding pregnancy discrimination at work in the UK means recognising both the obvious decisions and the quieter changes in opportunity, pay and treatment.
The key is to separate discrimination protection from related rights concerning antenatal appointments, workplace safety, maternity leave and dismissal. They overlap, but the legal tests and deadlines are not always the same.
When does pregnancy discrimination become unlawful?
In England, Scotland and Wales, the Equality Act 2010 makes pregnancy and maternity a protected characteristic. Unfavourable treatment because of pregnancy, pregnancy-related illness or maternity leave can be unlawful. Unlike many other direct discrimination claims, you do not need to identify a colleague who was treated better.
The discrimination protected period begins when pregnancy starts and usually lasts until maternity leave ends or the employee returns to work. The employer must know, or reasonably be expected to know, about the pregnancy for pregnancy-specific discrimination protection to apply. Some later decisions can still be unlawful where they stem from events during that period.
Separate sex discrimination rules may apply to treatment outside that period, including certain breastfeeding-related problems. Northern Ireland has its own equality legislation and tribunal arrangements, so the procedures below chiefly concern Great Britain.
Pregnancy discrimination examples that are easy to miss
Warning signs include withdrawing an agreed promotion after a pregnancy announcement, excluding someone on maternity leave from a restructuring consultation, marking pregnancy-related sickness as ordinary absence in a disciplinary decision, or reducing a zero-hours worker’s shifts after they report morning sickness.
Consider a project manager with strong performance reviews who announces her pregnancy in March. In April, she loses responsibility for a major client because her manager says the team needs “continuity”. That explanation does not automatically prove discrimination, but the timing, earlier reviews and emails about the handover may provide important evidence.
Antenatal care, sickness and safe working conditions
Eligible pregnant employees have the right to reasonable paid time off for antenatal care, including appointments and certain recommended classes. An employer should not penalise someone simply for using that right.
Once informed of a pregnancy, an employer must assess relevant workplace risks and take appropriate action. This might mean adjusting duties or hours, offering suitable alternative work, or, where legal conditions are met, suspending the employee on full pay if risks cannot otherwise be avoided.

Maternity discrimination during leave and on return
Maternity leave does not mean disappearing from the organisation’s decision-making. Employers should include affected employees in relevant promotion opportunities, redundancy consultation and important workplace communications without placing pressure on them to work during leave.
Return-to-work rights depend partly on the length of maternity leave. After ordinary maternity leave of up to 26 weeks, employees are generally entitled to return to the same job. After a longer period, they are still normally entitled to that job unless returning is not reasonably practicable; any alternative must be suitable and on no less favourable terms.
Pregnancy dismissal and redundancy protection
Dismissing an employee because of pregnancy or maternity leave can be automatically unfair and may also constitute discrimination. An automatically unfair pregnancy-related dismissal claim does not generally require two years’ service. Genuine misconduct or a legitimate redundancy situation is different, but employers must still act fairly and lawfully.
In a redundancy exercise, eligible pregnant employees and new parents receive priority for any available suitable alternative vacancy. For pregnancy and maternity, this additional protection generally starts when the employer is told about the pregnancy and can continue until 18 months after birth. It does not guarantee that an existing job can never be made redundant.
That redundancy priority period is different from the Equality Act’s pregnancy discrimination protected period. Confusing the two could lead someone to assume their rights ended on their first day back, or that they cannot lawfully be made redundant at all.
What evidence should you keep?
Start a dated record as soon as something feels wrong. Note what happened, who was involved, what was said and how it affected your work. Preserve material lawfully, respecting confidential information and workplace policies.
Useful evidence includes earlier performance reviews, recruitment or promotion feedback, rota changes, relevant messages, sickness records, redundancy scoring and the employer’s maternity policy. Record when you informed your employer of the pregnancy and retain any acknowledgement.
Ask neutral, specific questions in writing: “What criteria were used to reassign my client account, and when was that decision made?” A clear answer may resolve a misunderstanding; an inconsistent one may help explain a pattern.
How to complain and pursue a legal remedy
You can raise concerns informally where appropriate, then use the employer’s grievance procedure if the issue remains unresolved. Explain the decisions you challenge, attach your chronology and say what outcome you seek. Possible solutions include restoring duties, reconsidering a promotion, correcting records or agreeing compensation.
If internal steps fail, an employment tribunal claim may be possible. In Great Britain, most tribunal claims arising from acts on or after 1 October 2026 have a six-month-minus-one-day limit. For most acts before that date, the previous three-month-minus-one-day limit continues to apply. Multiple incidents can complicate the calculation.
Usually, you must notify Acas for early conciliation before making a tribunal claim. Starting a grievance does not stop the clock; timely Acas notification can pause the tribunal deadline under the applicable rules. In Northern Ireland, work-related discrimination complaints generally retain a three-month limit and use the Labour Relations Agency instead.
A successful claim can lead to compensation for financial loss and injury to feelings, and potentially recommendations or other relief depending on the claim. There is no automatic payout: evidence, liability and the consequences of the treatment matter. Specialist advice is especially useful where dismissal, multiple claims or an approaching deadline are involved.
Frequently asked questions
Can I be dismissed while pregnant?
Yes, dismissal can occur for a genuine lawful reason, but dismissal because of pregnancy or maternity is prohibited. The employer must comply with the applicable dismissal and redundancy rules.
Do I need two years of service to complain?
No. Equality Act discrimination protection does not require two years’ service, and pregnancy-related automatically unfair dismissal claims generally do not either.
Can I challenge a promotion decision made during maternity leave?
Yes, if pregnancy or maternity leave influenced the decision unlawfully. Keep the advert, selection criteria, feedback and any messages explaining the decision.
What if my complaint concerns Northern Ireland?
Seek guidance from the Equality Commission for Northern Ireland or the Labour Relations Agency. The legal framework and claim procedures differ from those in Great Britain.
Conclusion
Pregnancy discrimination is not limited to losing a job. It can shape assignments, opportunities, sickness decisions and the return from maternity leave. Understanding the different protections, documenting changes early and checking the correct tribunal deadline can turn a vague concern into an informed decision about what to do next.
