HI, The best place to check is the direct.gov site. You would most probably be able to find this on the website if not give them a ring. I have got three children and can confirm that you earn holiday's while on maternity leave. So as a teacher I would assume that you would be entitled to the same. As for the back to work days, as far as I am aware you get paid for these and it does not affect your maternity pay. Hope this helps.
