Pregnancy and maternity discrimination claims: helpful evidence and tips

If you’ve been treated unfairly by an employer because you’re pregnant, had a baby, or taken a period of maternity leave then you could have been discriminated against.

Pregnancy and maternity discrimination is unlawful under the Equality Act 2010. If you’ve been discriminated against you could bring a discrimination claim in the Employment Tribunal.

This page explains what evidence may be useful if you want to make a claim in the Employment Tribunal for pregnancy and maternity discrimination.

How to succeed with a pregnancy and maternity discrimination claim – key points

If you want to succeed with a claim for pregnancy and maternity discrimination you need to show that you have been treated unfavourably because:

  • You are pregnant
  • You are suffering or have suffered from a pregnancy-related illness
  • You are on maternity leave (or intend to take a period of maternity leave, or have taken a period of maternity leave)

In order to show unfavourable treatment you need to show that you have been subjected to some form of detriment – this could be, for example, that you have been denied a promotion because you are pregnant, or that you have been dismissed because you intend to take a period of maternity leave.

As well as showing that you are pregnant (or are suffering from a pregnancy-related illness, or on maternity leave, or have taken or intend to take a period of maternity leave), you have to link the unfavourable treatment that you have been subjected to and your pregnancy – you need to show that the “reason why” you have been treated the way that you have is because of your pregnancy or period of maternity leave.

Useful evidence in a claim for pregnancy and maternity discrimination

The following evidence could be useful in an Employment Tribunal claim for pregnancy and maternity discrimination:

  • A chronological breakdown of what has happened, when, and who was involved
  • A copy of your MATB1 form (showing your estimated due date), as well as evidence of when you gave this form to your employer
  • Evidence of when you first informed your employer that you were pregnant (for example diary notes, emails, and notes of meetings)
  • Evidence of any formal or informal complaints that you have made to your employer about unfair treatment (for example diary notes, emails, and notes of meetings)
  • Evidence of how you have been treated unfairly by your employer (for example diary notes, emails, statements of colleagues, and notes of meetings)
  • A copy of your employer’s equality policy, staff handbook, and maternity policy (if your employer has such documents)
  • Details of what training your employer has implemented on equality and diversity in general as well as, specifically, how to treat pregnant women in the workplace and how to deal with periods of maternity leave
  • A copy of any risk assessments that your employer has undertaken (whether because of pregnancy or otherwise)
  • Evidence of how other employees who are pregnant or have taken a period of maternity leave have been treated – you can use this to argue that your employer has a practice of treating employees who are pregnant or on maternity leave unfavourably
  • Evidence of how other employees who are not pregnant or have taken a period of maternity leave have been treated – you can use this to potentially argue that your employer has a practice of treating employees who are pregnant or on maternity leave less favourably

10 tips on what you should do if you think you are being discriminated against because of you are pregnant or on maternity leave

The following types of evidence are useful to gather if you are thinking of bringing a claim for pregnancy and maternity discrimination:

  1. Take notes of any meetings, discussions, and telephone calls which are relevant to your claims
  2. Keep a diary of incidents of unfair treatment that have occurred – what conduct occurred, when it occurred, and who was involved
  3. Make informal or informal complaints that you believe you are being treated unfairly because you are pregnant or on maternity leave
  4. Keep evidence of any complaints that you have have made about unfair treatment in the workplace, as well as the outcome of such a complaint
  5. Make recordings of meetings or discussions on your smartphone – this kind of evidence can be crucial to demonstrate exactly what was said and by whom
  6. Keep copies of emails and letters (as well as any other documents) which are relevant to your claim – if these documents are on your employer’s computers or systems then you should think about downloading copies (in case your employer removes your access to these computers or systems)
  7. Keep your medical records relevant to your pregnancy and period of maternity leave (you may need to rely on these in the claim)
  8. Obtain and/or keep evidence of any upset or psychological harm you have suffered because of the discrimination (this will be relevant to remedy (how much money you might get if you succeed with your claim))
  9. Keep evidence of any discussions that you have had with ACAS or your employer about settlement of your potential claims
  10. You could look at making a subject access request to obtain your personal data – this may provide you with useful information regarding your claim

    The service I received was friendly and professional. I appreciated the timely communications and Mel was always available for any questions I had. I'd definitely recommend Redmans and will use them in a heartbeat should the situation arise again.

    Redmans Solicitors recently helped me navigate a recent employment termination settlement agreement. Chris Hadrill is very professional and you will be in good hands with him. I score Redmans 4 out of 5 because things had to move fast and felt the team member assigned to my case wasn't very responsive at times. Having said that, I was very happy with the outcome and have no hesitation in recommending their services.

    I was made a settlement offer by my employer to terminate my emplyment early. Redmans helped me understand the offer, and ensured that it was fair for someone in my position. They made a very stressful situation much easier. Excellent service.

    I can highly recommend Redmans. The service was professional and prompt and I would not hesitate to use them again. Thanks

    Overall I am satisfied with the performance from Redmans. The reason I have given 4 stars is that I had quite a lot difficulty in contacting the representative which was initially nominated for me. However, when I contacted Chris instead, he was excellent over the phone and secured a great outcome in short order. I would recommend Redmans Solicitors.

    Chris and Redmans were a great help. Effective and efficient, quick response from my first enquiry and then straightforward and attentive throughout with ultimately a positive outcome. I will use them again and recommend them.

    I don’t normally write reviews, but thought it was time on this occasion. Just wanted to say that I highly recommend Redmans - especially Rana Tandon, who helped me navigate around my employment contract. Rana was meticulous and thorough and all over my needs. Would I use Redmans again ? ..absolutely

    Very thorough and professional service. I was very nervous about my employment case, as I had never dealt with anything like it before. However, the solicitors who handled my case made sure I understood everything. I was never kept in the dark and Redmans kept me constantly informed about what was going on with my case. I would definitely recommend Redmans Solicitors

    Chris and Sacha were great throughout the entire process. Chris was very helpful once the initial discussions with my company began and before we agreed there was a case. Sacha was very responsive, patient and helpful throughout ensuring I felt I had the right information to make the best decision on next steps. A close friend and wife have both used Redmans in the past few years for unfair dismissals and the service continues to be first-class and I would strongly recommend them again. They definitely help reduce the anxiety that comes with uncertainty around new processes and situations. Thank you!
