I am looking for a bit of clarification regarding the provision of cover for colleagues who are off long-term. I had assumed that the LA funded supply when the duration of a teacher's absence had exceeded some threshold point. Has this changed? We are covering internally for a colleague who has been absent for more than 4 weeks and are now wondering if this should be happening. Increasingly we are also doubling up classes, often at short notice. This has been stressful as it upsets lesson planning significantly. I should add that I work in the ASN sector.
