Hi, For the fifth consecutive week, I am writing cover for an absent colleague. It is common knowledge that she will not be coming back, and as she has been signed-off ill she has not been setting her own cover. The school have employed a subject specialist to cover her lessons, but as yet he is not being paid to mark or plan. And now a second colleague has been signed off sick! Next week I'll be writing cover for 17 lessons, as well as teaching 20 of my own. I'm the second in the department, the department head will be writing cover for 10 lessons in addition to my 17. My question is this: as second in department, on M6 and with TLR2a, do I HAVE to do this? Is it legal?
