5.6 x 2 is not 11, it's 11.2 and it can not be rounded down.
With regard to redundancy, what I was trying to establish is if you are getting maternity leave, or if the job is ending before you go on maternity leave.
Do you qualify for SMP? I think you do.
"Find the Sunday before the day your baby is due or the due day if that is a Sunday. Count back 15 Sundays from there. This Sunday is the start of the 15th week before the week your baby is due ? it is known as the Qualifying
Week."
Maternity Action says:
Do I still get SMP if my job ends after the 15th week before my baby is due?
Yes, you can still get SMP as long as you are employed in the 15th week before your baby is due and you meet the normal qualifying conditions. It doesn?t matter if you are off sick or on holiday in that week.
Once you have qualified for SMP, you are entitled to receive it for the full 39 weeks. This is true even if you are made redundant, you leave your job or a fixed term contract comes to an end at any time after the 15th week
before your baby is due or during your maternity leave.
They also say
*Can I still get SMP if I am dismissed or made redundant?
You can still get SMP if you were employed in all or part of the 15th week before your baby is due and you meet the qualifying conditions for SMP. You are entitled to receive SMP for the full 39 weeks regardless of when your job
ends. Your employer can pay the SMP in a lump sum but they may have to pay more National Insurance.
SMP can be offset against contractual redundancy pay or against statutory or contractual notice pay but not against statutory redundancy pay. In some cases, your employer may make a payment in lieu of notice but they can only do this if it is stated in your contract. Your employer cannot offset SMP against a payment in lieu of notice.
There will be contractual notice if your employer is ending your contract. Have they given you a finishing date?
I think what you are trying to do is to finish the job on the finishing date then have the holiday then have SMP start after the holiday. Is that right?
What happens about the holiday you build up whilst on maternity leave, or is it a case that you lose that because the job no longer exists. Anyone know?
Does the family use a nanny payroll company? They should be able to advise the parents about what payments will be necessary and what holiday you need to have taken/or get paid for.
ACAS says "Accrued holiday on termination need not to be rounded to the nearest half day ? payment can be made for the exact amount of leave accrued."
So with annual entitlement of 11.2 days and none being taken, on termination at the 6 month point in the holiday period, then you would get 5.6 days of holiday pay on termination.
Would the parents round up, to 6 days? Maybe they would, maybe they would not.
Maternity leave gets a bit complex, so have the parents talked to their payroll provider? That may be the first step and if you will be working right up to the termination day, the payroll company could be told that plus told that you would be having holiday added on at the end, then calculate the SMP and determine how the SMP will be paid (such as in lump sum).
To be honest this stuff is beyond me, the SMP bit I feel complicates it. Maybe someone else will be able to give you more sensible advice and know about how SMP affects things.
