Join the club!! I have been asked to rewrite two schemes of work with 15 lessons in each one for years I will not be teaching next year... it is unfortunate but the way life goes I think sometimes... (especially when some HOD's are lazy and can't be bothered to do it themselves!) - I certiainly am not writing Lesson plans though (which seems to me what your HOD is asking you to do?) - short-term planning is the responsiblity of the teacher who is taking the lesson! On the bright side, look at this way, you may not teach the subject, but when you are applying for jobs remember to state clearly that you wrote these SOW's.. it may just give you the edge over someone else!
