Hi, I'm thinking of doing supply this September and live on Herts /Essex border - Harlow, Hertford, Bishop Stortford, Ware side. Does anybody know a good agency for these areas and would there be enough work for approx 3 days per week. I'm an experienced English teacher. I don't want long term supply as I don't want to be planning and marking as I've had enough of it to be honest. Any advise would be useful.
