A teacher jailed for firing an air pistol near a group of youths is to claim unfair dismissal from her teaching job.
Linda Walker was convicted of affray and possessing a firearm
Linda Walker, 48, was dismissed in May from her post at New Park High School in Eccles, Salford, after a disciplinary hearing.
She lost an appeal against the sacking last month.
The NASUWT teachers' union said on Tuesday that it planned to launch a tribunal claim on behalf of Mrs Walker.
Ms Walker, 48, was convicted of affray and possessing a firearm in March. She said she fired the pellet gun after the youths had terrorised her family.
Ms Walker was jailed for six months but freed on appeal on 4 May.
Chris Keates, NASUWT General Secretary, said: "NASUWT intends to pursue all appropriate courses of action to seek redress for Linda Walker.
"She has faced the trauma of a court hearing, imprisonment, and the anxiety of internal school disciplinary proceedings on her release.
"Whilst the union cannot condone taking a gun onto the streets, it is difficult not to understand her extreme distress as a result of months of harassment and abuse.
"No action was taken against any of the youths at whose hands she had suffered.
"There is something inherently wrong with a situation where the victim's ordeal is greater than those who carried out the abuse in the first place."
