I took my employer to tribunal for pg related sex driscrimination - as soon as I announced I was pg, they suddenly changed my role and moved me somewhere sleepy...
Don't know if you're pursuing... but I think it is tough... the whole process drags on - my simple case lasted nearly a year, and I don't think that is unusual...
Employment Tribunals try to encourage a negotiated settlement, so once I approached them, they allowed my employer to argue they wanted to try the formal internal process first... even though I have been unable to get them to do it prior to submitting my complaint to the ET. so by the time we got to tribunal my DD had been born!
I represented myself at my case management hearing - which is a short first hearing to establish whether you have a case to present, and to assess how many days will be needed. The Chairperson said they would help all they could, but they strongly advised me to get a lawyer! Employment tribunals were meant to be set up so that you coudl self-rep., but in practice is hard as the law is complex, and the other side will probably have a barrister - mine did!
I was fortunate in being able to claim on the legal expenses of my house insurance... check your policies, lots do contain provision for legal disputes...
The day before the tribunal - so all the work is done, and you're revved up to go... they finally made an offer above what we expected to win... At this point, your insurers lawyers recommend you take it, and the game is over...
The pay out was a bit hollow. Although it was several thousand pounds, we were unable to negotiate any changes to practice or policy - I wanted to make things better for other women... no one said sorry, and it was a hell a lot of grief at a busy and emotional time of my life...
Would I do it again... hmm... maybe... I'm a stubborn so and so.... stressful though!
