Smox and ItsallisnowaFeegle. - Please let me know what advice and tips you are after and if my experience to date can help you I'll give you my feedback. I also have some learnings on the procedure which I would be happy to share if you are at the ET stage and proceeding to a hearing. In the meantime, here are some general thoughts which may be helpful:
I am pleased that I have pursued the case to this point - however, given the timescales involved from lodging an ET1 form (the legal document submitted to the employment tribunal office (ET) notifying that you wish to proceed with a claim) to the case being heard and completed, I can understand why many individuals decide to settle with the other party - often for a lower sum than anticipated. I lodged my ET1 in early Dec 2012 and as noted I am still at the 'liability stage' 6 months on - therefore the process is long, costly and stressful at times.
To begin with, I would recommend anyone thinking about this course of action should take independent legal advice. You need to see a solicitor that knows employment law, and will be truthful about the merit of your claim. No win no fee arrangements are not helpful at this stage.
I took legal advice at a very early stage - and I am glad that I did. I would not have known how strong my case was, or even what documentation was important, and would not have had all the information to hand to lodge the case.
Truth be told, from a purely financial perspective I did consider representing myself at the hearing - mainly as so many websites say this is feasible and the process is geared to being far less informal than a court of law. However, my experience has been that the ET hearings are quite formal, follow legal rules, and without any prior knowledge of the system I believe it would be daunting.
Constructing the legal arguments, especially on discrimination on the grounds of maternity has been very complex. Even remembering what evidence has been led by either side over a 5-6 day hearing is not straightforward. Cross-examination is extremely difficult, even with a experienced litigation lawyer. It would be nearly impossible to do this effectively yourself, so your case would be compromised. All in all, I would not recommend bringing an ET claim without legal representation.
It is a long process which is daunting at times. However, if your case is of strong merit and you have not been able to resolve the situation with the other party - stay strong and remember you have done nothing wrong. You have simply exercised your right to have a family - if the employer has not treated you fairly during this time then it is their issue in the long-run and one they should be answerable to.
