Dear @LHLW
It is unlawful for your employer to treat you unfavourably because of your pregnancy or on maternity leave. As you are on maternity leave you are in what is called a “protective period”. This covers the period from when your pregnancy begun and ends when your maternity leave concludes (excluding any annual leave you take before returning from annual leave). During this period, you can claim pregnancy and maternity discrimination if you are treated unfavourably by your employer and your pregnancy/maternity leave does not have to be the only or even the main reason for your unfavourable treatment, but it must be a 'material influence' on your employer’s conscious or subconscious decision-making.
A benefit of being in the protected period is that a comparator is not required. This means that the test is whether you have been treated ‘unfavourably’, rather than ‘less favourably’ as is required for all other protected characteristics.
Advertising your role
Should it be ambiguous, you may first be best asking your employer whether the advertised role is in fact for your position. You also want to know why it covers 12 months considering your return date in 4 months time.
If the ad specifies that it is for maternity leave cover it could enable your employer to give notice earlier to terminate the contract if you return to work earlier or your employer may have decided that they are unable to recruit to a role for such a short period and will maintain both roles for a period. In any event I suggest getting some clarity from your employer.
If you are returning during your ordinary maternity leave (first 26 weeks), you have the right to return to the same role on the same terms of employment and conditions as if you hadn’t been absent. If your employer does not allow you to return to the same job you could have a claim for unfair dismissal, automatic unfair dismissal and/or maternity discrimination.
If you are returning during your additional maternity leave (more than 26 weeks), you have the right to return to your role unless your employer can show it is not reasonably practicable for you to return to the same job, although you should be offered a suitable job on similar terms and conditions. For example, if your role still exists and this has been given to someone else hired in your role, this would amount to discrimination and unfair dismissal.
Treatment while pregnant
In respect of your employer’s treatment of you while pregnant (still during your protected period), such as excluding you, your claim would be that this resulted in you suffering a disadvantage/detriment. However, whether you are in time to bring a claim for these earlier acts of discrimination is set out below (Next steps).
Flexible working request
You mentioned that you put in a flexible working request to work on a part-time basis. Any claim you may have against your employer in their dealing with your flexible working request depends on whether this was a statutory request or an informal one.
Presuming that you made a statutory flexible working request, you should receive or should have received a response to your request within 3 months. The tribunal would also look at whether your employer dealt with your request in a reasonable manner, such as inviting you to a meeting to discuss your request (why you want part-time hours, how any problems your request, if granted, could be overcome, and other options should your request not be possible e.g. other working patterns), and gave a valid reason (of which there are 8) for refusing your request. If your employer has failed to deal with your request in this matter, you could bring a claim for breach of the statutory flexible working regime (although a successful claim of this type would include only limited compensation of up to 8 weeks' pay capped at the statutory amount) and/or indirect sex discrimination. You should include any complaints you have in respect of how your employer has dealt with your request in any grievance you may raise.
Unfortunately, the right to request flexible work is weak and is a right to 'ask'. Your employer may be able to justify a refusal for one or more of 8 legal business reasons. You have mentioned that you stated in the request that you would consider other roles. Your employer should be considering how you can fulfil your existing role in a way that meets your childcare needs. If you think your employer is justified in refusing your request or it would genuinely be difficult to do your job in the way you are asking, you can ask your employer to consider you for other roles, but they do not have an obligation to provide other work. Your strongest legal right on return from maternity leave is to return to the same job on the days/hours that you were working immediately prior to your maternity leave.

Time limits
The time limit for starting a discrimination claim is three months, less than one day, from the act or last in a series of acts of discrimination. Whether you can rely on previous instances of discrimination, prior to your maternity leave, depends on whether you can show a continuous course of conduct. A tribunal can sometimes accept a claim out of time if you can show that it is 'just and equitable', however, you cannot rely on an extension of the time limit, and I recommend making a claim on time wherever possible; otherwise, your claim may fail.
Your time limit to bring a claim for their response to your statutory flexible working request is three months, less one day, from when your employer made their final decision. If your employer didn’t make a decision within 3 months of your request, your limitation is 3 months, less one day, from their deadline to respond to your request. However, if you are continuing to negotiate a part-time return to work with your employer, you may want to continue that process rather than start a claim against your employer at this stage.
Unfortunately, there are limited options for free representation for employment tribunal claims, and I suggest seeking further advice on the merits of any claims and likely compensation before embarking on a claim.
Bringing a grievance/claim
If you want to take further action, you are expected to make reasonable attempts to try to resolve the issue with your employer first. Although it is advisable to try to resolve matters informally initially, it is apparent that you have already tried this to no avail. Whilst, raising your concerns in writing will set the groundwork for any future claim you may bring, it is also important to bring a grievance to prevent any potential compensation from being reduced. This includes appealing the grievance outcome should it not resolve your concerns, but being mindful of the time limit above.
You should also be aware that bringing a claim is likely to damage your employment relationship as it makes employers defensive, often entrenching the issue further, and does not usually end well. Therefore, you want to seriously consider whether to bring a grievance or whether there is scope for further discussions to resolve things amicably. If you do have any further discussions with your employer, be sure to take a note either at the time or as soon as possible thereafter.
If you do want to submit a claim to the employment tribunal, you will need to first go through ACAS early conciliation before the expiry of your time limit: https://www.acas.org.uk/early-conciliation ACAS may be able to resolve the issues with your employer, for example, by helping you to negotiate an exit settlement with your employer, which would avoid the risks and uncertainty of employment tribunal claims.
I hope this helps.
