The night went well. Nobody became sick or was injured.
I had three good aides (the total amount possible) and one weak link. Attempts at redirecting her to do work instead of sitting on her butt were met with:
"I have to do [blank]? Nobody told me that."
"Isn't that somebody else's job?"
"But it's only 12:00." Or 1:00 or 2:00.
Repeated reminders to perform tasks were met with sighs and rolled eyes, but little actual work.
The repercussion is that the other aides see her doing nothing and expect me to fix it. I can't make her work. She's the norm, not the exception. Administration will not take a hard line with these do-nothingers. I don't know how else to handle such "workers."
