After-School Cleaning Duty

The final bell rings, signifying the end of the school day. While most of the kids are gathering their things and preparing to head home, a small group have resigned themselves to staying behind, as it is their turn for After School Cleaning Duty. They must make sure that the desks are straightened, the chalk board is cleaned, dust is beaten out of erasers, and the trash cans are emptied before they can leave. For some, this assignment may have been given as punishment for getting caught sleeping in class. For others it may simply be their turn for duties shared amongst all the students in the class, or part of Class Rep and club membership responsibilities.

A common trope in school-life stories, After School Cleaning Duty serves to get a single character or small group alone, away from their peers and outside of teacher supervision. This could be a setup for an accidental romantic meeting between the male and female leads, or a chance for the Alpha Bitch or The Bully to torment the character without fear of interruption. In Horror stories, an empty school can become a creepy setting for any student assigned to cleaning duty who is unfortunate enough to be stuck there alone with the Monster of the Week.

An Extreme Doormat will often accept cleaning duty without complaint, even if the job is passed off to her by another student. More rebellious students will seek to get out of After School Cleaning Duty if at all possible... failing that, they will take the opportunity to see what other kinds of trouble they can get into while no one else is around.

Rivals forced into cleaning duty together may get the chance to find out that they're Not So Different.

This trope can lead to characters being accidentally locked in a storage closet, especially if a potential love interest is helping out. After-School Cleaning Duty can be especially troublesome for students who double as super heroes, as an ill-timed battle or a misuse of supernatural abilities can leave the area they were supposed to clean looking even worse the next day.
