OMAHA, Neb. – An Omaha woman is banned from her child’s former elementary school after the principal alleges she head-butted him during a tirade last week.

The woman was not identified in media reports, but Omaha Education Association President Chris Proulx alleges she was called to Fontenelle Elementary School by Principal Eric Nelson last Friday because her 11-year-old was among a group of students involved in a food fight at lunch, KETV reports.

The 49-year-old woman allegedly arrived at the school in a rage, and yelled and cursed at staff before she started roaming the halls, opening classroom doors and chastising teachers for not doing their jobs.

“We don’t need our kids to see adults acting this way,” Proulx said.

Nealson apparently attempted to quell the disturbance, but the mother got in his face and head butted him hard enough to leave a mark. The principal was not seriously injured in the incident, did not seek medical treatment, and did not miss work because of it, according to district officials.

The incident is “something that puts a lot of people at risk, and we can’t have it in our schools,” the union president said. “Violence is never an acceptable response to being mad or frustrated.”

Proulx alleges violent outbursts from parents are becoming more common in the district. Police were apparently called to the school but no charges were filed against the mother. KETV reports “the principal told police the same parent had similar outbursts last year, and he tried to get her banned, but the district gave her a warning then.”

“There’s no code of conduct for parents,” Proulx said. “It’s only for students, so these things are taken very much on a case by case basis.”

Proulx believes district officials should take some sort of action to prevent similar incidents in the future.

“We need to figure out what we do to address this to make sure it doesn’t happen again in any of our schools and not just with this parent,” he said.

Parenting.com also weighed in on the episode, and pointed out the child was transferred to another school at the mother’s request.

“It’s truly sad this mother thought she could solve a problem using violence against the principal, especially since her child is looking up to her to set a good example as to how to act in school,” the parenting site opined.

“It’s scary too, since there’s no code of conduct to regulate parents’ bad behavior.”

Parents posted mixed reactions to the incident online.

“No code of conduct? How about the law?” Jesseka Zeigler posted to Parenting. “Pretty sure head butting someone is assault.”

“And there is not code of conduct to regulate the staff’s behavior either,” Billie Jean Washburn wrote. “In my childrens’ school handbooks it specifically says that teachers have the right not to be verbally abused or physically abused, threatened in any manner. True … however, why does it not state the children have the same right? Because they don’t. They are money bags walking in the door. … Some teacher do monitor the children but most do not, they sit on their iPads, other devices, while the children basically teach themselves. So, whatever happened here to make this parent that mad, well I don’t think it was just the food fight at all. I’m betting she’s put up with a whole lot of shiat before she snapped and did this!”

“This is the sense of entitlement kids are given when their parent(s) behave this way because the KID was acting up. I feel bad for the principal, the teachers, the other students in classes, but mainly the child of this woman,” MommyOf2 posted to KETV. “I wonder what he deals with at home if she can act like that out in public.”

“The sad thing is the example that the parent is setting for the kid. They will think that this is ok. This seems to be a trend,” Mrs. Peacock wrote.

“I’m involved in a youth football program and we had a parent that was swinging at coaches after a game and as the coaches were walking off, this parents kids were flipping the coaches the bird,” she continued. “The kids were 10. This is the new culture that we live in ladies and gents!”
