This computer/tablet/smaphone app matches teachers looking for work with schools looking for teachers. The progression would see a many other offices/businesses acquiring relief staff. Teachers available for temporary work download the app and upload their personal details. Schools download the app and provide a context overview - location, co-ed / single sex, year levels, sector etc. When a staff member calls in sick the person responsible for organising relief staff brings up the app, refines the search by region and selects a candidate from the list.
