Substitute science teacher Alex Dolan took covert footage of students in London and Leeds to document and uncover deficiencies in the local school system.
And what did she get for her trouble? Why, she was found guilty of professional misconduct, of course! Didn't she ever heard of the adage "no good deeds go unpunished?"
Alex Dolan recorded the footage covertly at four schools in London and Leeds in 2005, exposing apparent attempts by the school to dupe Ofsted inspectors.
A General Teaching Council panel found her guilty of taking advantage of pupils, breaching their trust – and that of colleagues – and abusing her position.
Dolan was praised at a hearing of the panel last week for showing integrity, and acting as a whistleblower to expose conditions in the schools in which she had taught.
But in its judgment, the panel said it did not accept that the public interest issues raised by the film Undercover Teacher justified the use of covert filming.
