Stick with term time job or take new position?

[SpinMill]

Current job working 5 days a week term time only. Opportunity of a new position working 2.5 days a week all year round. New position is more responsibility and better paid so works out the same salary for fewer hours.
Stuck on what to do, new job would mean arranging holiday childcare wheras at the moment I have holidays off with DC.
Also worried about how easy it would be to book annual leave in school holidays.

How many annual leave days would you get with the new role?

I'm not sure yet, they've said 'generous annual leave entitlement'.

How old are your DC?

Same salary, fewer hours = higher childcare costs to cover the holidays.
= less money for fewer hours than it appears.
How does this actually work out?

DC is 8

Ariela that's true, however my childcare costs would be less during term time as I could drop off and collect on non working days.

I've recently been in a similar position, and chose to leave the term time only job. My reason was that in five years time I'd still be earning the same with no prospect of advancement, whereas the private sector looked more promising. I have a 7 and 10 year old.
