Union leaders have thrown their support behind a teacher sacked after publicly criticising one of Tony Blair's favourite heads.
Eileen Hunter was dismissed from the International School in Birmingham in November last year after saying Sir Dexter Hutt, who leads it and two other schools as part of a federation, was undermining staff morale and had imposed draconian discipline.
Ms Hunter, NUT representative at the school, was dismissed for gross misconduct following an accusation that her comments, published in The TES, had brought the school into disrepute.
A leaflet circulated to delegates said: "For speaking out at school union meetings and last year's NUT conference, Eileen was charged with jeopardising the future of her school. If this is grounds to lose your job, then this is a threat that could be made... to many active reps."
