Hi, I'm hoping someone can give me advice about extending maternity leave before I talk to my employer. I started maternity leave in May 2010 and said I would be taking 9 months, returning Feb 2011 (and I confirmed this with my manager last week). But my childcare arrangements have fallen through, and I now want to take the full 12 months. I would only be giving 4-weeks notice that I'm not coming back as stated. What is the legal position on this? Having searched legal sites, most talk about employees wanting to come back early, not delay! Thanks.
