Teacher Linda Walker, who was jailed for firing a pellet gun near a group of youths, has been sacked from her job.
Linda Walker said the youths had terrorised her family
The 48-year-old was suspended from her job at New Park High School in Salford after being convicted of affray and possessing a firearm in March.
Ms Walker, from Urmston, Greater Manchester, was jailed for six months, but freed on appeal on 4 May.
The teacher has decided to appeal against the decision by Salford City Council on Monday.
The mother-of-two, who had been a teacher for 25 years, appeared before a panel representing the city's local education authority which found her guilty of gross misconduct.
Freed on appeal
Cliff Anderson, regional coordinator of teachers' union NASUWT, said she planned to appeal, but would not be commenting further.
Jill Faker, director of education for Salford City Council, said: "Disciplinary hearings are confidential matters between the appropriate authority and the individual concerned.
"As a result, we will not be commenting on the case or giving out any specific information about it.
"As with other disciplinary matters, this case has been progressed in accordance with formal city council procedures."
Ms Walker said she fired the gun after the youths had terrorised her family.
Her trial was told she had received nuisance phone calls abusing her family, her garden shed had been broken into, and a car and her garden had been vandalised.
But no evidence was produced that any of the youths she confronted were involved in the vandalism.
Her case gained much public sympathy, with 10,000 people signing a petition calling for her release from jail.
Ms Walker later told a newspaper she felt "crucified" by what had happened to her.
At a hearing at the Court of Appeal, three judges gave her a conditional discharge, but refused her permission to challenge her convictions.
The special needs teacher left the hearing without comment and has seven days to lodge an appeal which will be heard by the school's governors.
