Teachers awaiting their disciplinary hearings were paid to sit in windowless rooms and--well, do nothing really--for the hours that they would otherwise be working. The New Yorker visited one last year:

It's a June morning, and there are fifteen people in the room, four of them fast asleep, their heads lying on a card table. Three are playing a board game. Most of the others stand around chatting. Two are arguing over one of the folding chairs.

[...]

One of [the teachers] pointed to a man whose head was resting on the table, beside an alarm clock and four prescription-pill bottles. "Look at him," she said. "He should be in a hospital, not this place. We talk about human rights in China. What about human rights right here in the Rubber Room?" Seven of the fifteen Rubber Room teachers with whom I spoke compared their plight to that of prisoners at Guantánamo Bay or political dissidents in China or Iran.

So yeah, next up: Guantanamo.
