For students, a day with a slacker substitute teacher can be a dream. If they fit the stereotype, you get to watch movies, play on your phone, or read to yourself instead of taking a grueling test or spending another hour of your school day immersed in difficult study.
However, for the teacher, leaving the class with an irresponsible substitute can completely throw lesson plans off track, and in some scenarios, leave your entire classroom in shambles.
In a popular Reddit thread, teachers shared stories of the worst substitutes they've had, and the anecdotes range from funny to deeply disturbing.
Back when I was a teacher, I had a sub decide my plans weren’t good enough for her and went rogue. She decided to show my students videos of animals giving birth on YouTube.
I taught English...
One sub made an elementary student cry insisting her own name was misspelled and made her stand up in front of the class and admit her name was spelled wrong. I asked that she not return but I still saw her around as other teachers had her sub.
