I am trying to avoid a situation where I am back at work, baby gets sick at creche, and I have to ask for time off to mind baby. I would prefer to take the unpaid leave off in the 'flu' months of dec and jan, and then be able to come back to work full time in feb or march.
If the employer tries to make me come back to work in dec and jan, and then grants the unpaid leave in march or april, this will be no good, as I will have baby started in creche, and will have to pay to keep the place.
