Iam a primary teacher at a high pressure school. I had my little girl in April and I'm due to go back in December. I really want to go back 3 days a week. In the past a mother asked to drop one day a week and was refused as it was though to impact the children too much. However now there is a job share with the DH and there was two teachers in another class previously. How do I write this letter? What do I need to say? Please help.
