There's a bit of a backstory. Bear with me.
Back in September, with the sterling assistance of MN, I appealed against an attempt to sack me for taking too much sick leave due to serious illness. However, the victory soon turned hollow as those involved in the plan to get rid of me turned really petty and nasty and made working there absolute hell.
Senior management and HR have responded by reorganising the way the department in structured and reconfiguring and my immediate line management to allow me to avoid any of those who were giving me hassle. If I were being cynical I could say this is partly a ploy to avoid me claiming disability discriminatin and constructive dismissal. However, I think there has been some real contrition and goodwill involved, as well as a genuine desire to keep me working there. There's a meeting Friday to discuss and finalise the arrangements,
What they don't yet know is that I'm pregnant. I found out in the midst of all the drama so am now 16 weeks and in no danger of showing yet.
I know that I don't need to tell them until 25 weeks, but I suspect that I will need to start maternity leave early at 30ish weeks due to the impact of my health on the pregnancy, which wouldn't allow them long to plan/prepare for my absence. However, I'm reluctant to tell them too early in case I lose the baby. I don't have a history of miscarriage, but I know that if I were to have one and they were to know, I would get such an unsympathetic response that I would prefer not to have to tell them.
So, should I tell them on Friday that I'm pregnant, even though I'm not yet legally required to? Or should I hold off and wait until the last possible moment?
And if I do tell them now, can management withdraw the new working arrangements on the ground that they didn't know I was about to go on maternity leave? If they did, would it be discrimination?
