About the film
The Rubber Room is a 2010 documentary film about the reassignment centers run by the New York City Department of Education, which the filmmakers claim exist in various forms in school districts across the United States. Allegedly intended to serve as temporary holding facilities for teachers accused of various kinds of misconduct who are awaiting an official hearing, these reassignment centers have become known amongst the "exiled" teachers subculture as "rubber rooms," so named after the padded cells of psychiatric hospitals.
