Several readers have pointed out that retired teachers are free to be outspoken, because they can’t lose their jobs.
This teacher explains what retired teachers did in one community:
In Rockford, IL, a group of retired teachers and parents heard the cry for help from their active teachers. They formed an organization (W.E.E.: Watchdogs for Ethics in Education), and set about doing fact-finding work: they researched, went to meetings and took notes, filed an FOIA, and then presented their facts via a fact sheet to the community. Their efforts–in large part–resulted in the departure of their reviled Broad superintendent! (The next one was better, and he also knew that W.E.E. was on the case!) So–get your retired teachers out there to work with parents and community members (don’t involve active teachers–they’re too busy teaching, and their jobs might be threatened), and have at it.
