Definitions
A substitute teacher is the temp worker of the education world — a fill-in instructor who covers a class when the regular teacher is absent. In North America and India this is the standard term, while the UK and Australia say 'supply teacher.' In student culture, the arrival of a sub is practically a national holiday: everyone suddenly forgets the rules, chaos erupts, and productivity drops to zero. The substitute teacher has become a cultural archetype — someone who has to win over a room of strangers every single day with zero context.
When the substitute teacher wrote her name on the board, the back row immediately started planning exactly how much they could get away with.

Relief teacher is the Australian and New Zealand term for what Americans call a substitute teacher and Brits call a supply teacher — the fill-in educator who shows up when the regular teacher is absent. Relief teachers are the unsung heroes (and occasional targets) of school days gone sideways. Kids universally recognize the relief teacher as a signal that normal rules are slightly looser, while the teachers themselves often face the challenge of managing a class that smells opportunity.
