I think the title explains all. Frankie does just about everything at Foster's and is the only employee there and yet somehow, I feel she is treated pretty badly, almost like a downright slave.
However, I think Herriman treats her the worst, ESPECIALLY in Destination: Imagination. What's worse is that he said it was Frankie's job to do everything without any respect. I mean, God! If anyone SAW him treating her badly as an employee, Mr. Herriman would be IN JAIL!!
