There's something about seeing a sub that makes some students turn off. Especially at the continuation high school.
Mr. H is not a popular teacher. He's strict. He requires his classes to work silently. And they resent him for it. So, when I show up, the class relaxes (read: I can't get them to do anything).
Actual student quote: "A sub? Good. I'm not going to do any work today."
But as luck would have it, it was Thursday. At the continuation high school.
I explained that if they wanted me to sign their buyouts, they had to do the work. And finish. (I've had students do one or two questions and think that's enough.)
But of course some students can't buy out. The student who said the above? Didn't do any work. Also, he didn't have a buyout.
Every student who had a buyout, however, did do the work. So, it was a win for me. Sort of.
