We are thinking that at the end of this school year we will probably review our childcare situation. We are currently paying pretty much for a full time nanny when both DCs are at school, so really for a few hours after school (I do morning school run) and for school holidays and emergency cover. We will probably make her redundant and use some combination of after-scool club, after school nanny, and/or DH working flexible hours a couple of days (so start and finish early). Holidays will require a bit more thought!
On the assumption that we get holidays figured out and decide to do this, my question is how soon should I tell our nanny? She has a 4 week notice period, and I imagine there is a timetable associated with a redunancy, but I was thinking of telling her as early as the new year with a view to giving her as long as possible to find something else (she has her own child so not every job will be suitable). Obviously there is a risk she will end up leaving early if she finds something. I wouldn't want her to leave before Easter (DH probably won't be able to work flexibly before then for various reasons) but could probably manage the summer term. Maybe I shouldn't tell her until Easter then? If she leaves before the end, would I be right to think i would not then have to pay redunancy? If she stays until the end but has another job to go to immediatiely, do I have to pay her redundancy in that case?
Any other pros and cons of telling her very early?
