The Rubber Room is the name for the places where New York City teachers who are under disciplinary investigation are sent to await their. For months -- sometimes years, and sometimes decades, these teachers go to "work" every day in a mostly bare room, and wait, and wait, and wait. Even if exonerated, many of these teachers are so stigmatized that they have to switch careers. Sounds like something out of Sartre or Kafka, but it's just New York.
Here's a documentary on the Rubber Room, made by an ex-teacher who was sentenced to it.
