DWP are getting more stringent when assessing claims for JSA from supply teachers. Some areas of the UK have, in the past, seen supply teachers made to disclose their total work hours for the previous year. My information is that other areas are now following suit. If they work out that your average work hours over a 12 month period amount to 16 hours or more, they classify you as ineligible for JSA. It is therefore important to only declare the paid hours you have worked: never include the lunch break as that is unpaid for everyone. Check your contract and pinpoint whether you are paid for a standard 5 hours when working a full school day. Keep diaries and payslips so that you can proe your past work schedule. Total up all paid hours over a year and divide by 52, not by the 39 school weeks. Keep an eye on it as it would be gutting to have worked just the one extra day that tipped you into the 16hrs+ on average per week and dienfranchised you from £67 per week or more in JSA in unemployed weeks.
