Workplace violence and student behaviour incidents

Workplace violence has become one of the most serious health and safety issues for school staff. Most of it comes from students, often young students or students with disabilities who are distressed and cannot express it in other ways. Some comes from parents and other adults, and some from intruders. The injuries range from bruises, scratches and bites to concussions, broken bones and lasting psychological harm. This lesson explains what the law requires, how schools assess and plan for violence, how staff can recognize and respond to escalating behaviour, and what happens after an incident. It is written with respect for the students involved: most behaviour that hurts staff is a sign that a student needs more or different support, and the safety measures in this lesson protect students as well as staff.

What counts as workplace violence

The OHSA defines workplace violence as the exercise of physical force by a person against a worker in a workplace that causes or could cause physical injury, an attempt to exercise such force, or a statement or behaviour that a worker could reasonably interpret as a threat to exercise such force. The definition does not depend on the intent of the person using the force. A seven-year-old who kicks an educational assistant during a meltdown has, for health and safety purposes, committed workplace violence, even though the child may not have meant to hurt anyone and would not be held responsible in any other sense. Recognizing this is not about blaming the child; it is what triggers the employer's duty to assess the risk and protect the worker.

What the law requires

Since 2010, the OHSA has required employers, including school boards, to deal with workplace violence through a set of specific duties:

• A written workplace violence policy, reviewed at least once a year.
• A risk assessment of the risks of workplace violence that may arise from the nature of the workplace, the type of work or the conditions of work, reassessed as often as necessary.
• A program that implements the policy, including measures and procedures to control the risks, to summon immediate assistance when violence occurs or is likely, for workers to report incidents or threats, and for investigating and dealing with incidents, complaints and threats.
• Information and instruction for workers on the policy and program.
• Where a worker can be expected to encounter a person with a history of violent behaviour, and the worker is likely to be at risk of physical injury, the employer must provide information about the risk, including personal information, but no more than is reasonably necessary to protect the worker.
• Workers can refuse work when they have reason to believe workplace violence is likely to endanger them, subject to the limit on teachers in Regulation 857 described in Lesson 2.

Assessing the risk

A board-wide assessment looks at the patterns: which schools, which programs, which roles and which times of day have the most incidents. Daniel's assessment shows, unsurprisingly, that the risk is highest in elementary schools, in specialized classes for students with significant behaviour needs, for educational assistants and kindergarten and primary teachers, and at transitions such as arrival, recess and dismissal. It also shows that some risk exists in every school: parents who become aggressive in the office, students fighting in secondary hallways, and people who enter the building without permission.

The most important assessments, though, are for individual students. When a student's behaviour has hurt staff or is likely to, the school develops a plan for that student.

In Ontario, this is usually called a safety plan, developed alongside the student's Individual Education Plan (IEP) where there is one. It is written by the principal with the teacher, educational assistants, special education staff, the family and, where involved, outside professionals.

A good plan answers practical questions: what are this student's known triggers; what are the early signs that the student is becoming distressed; what helps the student calm down; what staff should do at each stage; how many staff should be present and who; how staff summon help; whether staff need protective equipment such as long sleeves or kevlar arm guards; how the room is set up to give the student and staff space and exits; and what happens after an incident. Every person who works with the student, including supply staff, must know the parts of the plan they need.

Patterns in the incident log

Incident logs can reveal patterns that are hard to see day to day. Jenna and the resource room teacher at Willow Park keep a simple log of incidents with one student: the time, the activity, what happened just before, and the outcome. The program below summarizes six weeks of entries by time of day and by what happened just before.

# Summarize an incident log by time block and antecedent (what happened just before).
from collections import Counter

log = [
    ("08:50", "arrival"), ("08:55", "arrival"), ("10:40", "transition"), ("11:45", "noise"),
    ("08:45", "arrival"), ("13:10", "demand"), ("08:52", "arrival"), ("10:35", "transition"),
    ("14:20", "demand"), ("08:58", "arrival"), ("11:50", "noise"), ("10:42", "transition"),
    ("09:05", "arrival"), ("13:15", "demand"), ("08:48", "arrival"), ("11:40", "noise"),
]

def block(t):
    h = int(t[:2]) + int(t[3:]) / 60
    if h < 9.25: return "arrival (before 9:15)"
    if h < 11.5: return "morning"
    if h < 12.5: return "lunch"
    return "afternoon"

by_block = Counter(block(t) for t, _ in log)
by_cause = Counter(a for _, a in log)
print("Incidents by time of day:")
for k, n in by_block.most_common():
    print(f"  {k:22} {n:2} {'#' * n}")
print("Incidents by what happened just before:")
for k, n in by_cause.most_common():
    print(f"  {k:22} {n:2} {'#' * n}")

Incidents by time of day:
  arrival (before 9:15)   7 #######
  morning                 3 ###
  lunch                   3 ###
  afternoon               3 ###
Incidents by what happened just before:
  arrival                 7 #######
  transition              3 ###
  noise                   3 ###
  demand                  3 ###

Nearly half the incidents happen at arrival, and the most common trigger is the arrival routine itself. That finding changed the plan: the student now arrives ten minutes after the main bell through a quiet side door, is met by the same staff member every day, and starts with a calming activity he chooses. Incidents at arrival dropped sharply over the next month. The log also showed that noise at lunch was a trigger, and the student now eats in a quieter room with two classmates.

Recognizing escalation

Most violent behaviour does not come out of nowhere. It usually follows a recognizable pattern of escalation, and staff who know the pattern can often step in early, when calm, low-key responses work best.

At each stage, the response is different:

• In the calm phase, the work is prevention: predictable routines, good relationships, clear expectations and an environment that suits the student.
• When something triggers the student, staff can often remove or reduce the trigger: lower the noise, change the task, give a break.
• In agitation, the student shows early signs, such as pacing, refusing, withdrawing or raising their voice. Calm, low-key responses work best here: offer choices, give space, use few words and a quiet tone, and avoid power struggles.
• In acceleration, the student is arguing, threatening or throwing things. Staff keep a safe distance, stay between the student and the door only if it is safe, move other students away, and call for help using the agreed method.
• At the peak, the student may hurt themselves or others. The priority is everyone's safety: follow the plan, clear the room of other students if needed, and use physical intervention only as a last resort, only if trained, and only in line with the board's rules.
• In de-escalation and recovery, the student begins to calm. This is not the time to discuss consequences. Give time and space, then reconnect.

Summoning help and staying safe

Every staff member who might face violence needs a reliable way to get help quickly. Depending on the school, that might be a classroom phone or intercom, a two-way radio, a personal alarm, a code word called to the office or a panic button. The method must actually work in every room, including portables, gyms and outdoor areas, and staff need to know who will come and how fast. At Willow Park, the resource room has a radio, and the response team, the principal, the vice-principal and two trained staff, aims to arrive within two minutes.

Simple measures make rooms safer: furniture arranged so staff are not trapped in a corner, heavy or sharp objects stored out of reach, a calm space for the student, and at least one clear exit for staff. Staff should take off lanyards, scarves and dangling jewellery that could be grabbed, and wear the protective equipment the plan calls for.

Violence from adults

Some violence comes from parents, guardians, former partners of staff, or strangers. Offices are where most of it starts: an angry parent demanding to see a teacher, a custody dispute at dismissal, or someone who will not leave. Controls include a single controlled entrance with a buzzer and camera, office layouts that keep a counter between staff and visitors and give staff a way out, a code word to call the principal, a clear rule that staff do not argue with an aggressive visitor but call for help, and, when needed, banning a person from school property and calling the police. Threats against staff, including threats on social media, are reported and taken seriously.

After an incident

What happens after an incident shapes whether staff keep reporting and whether the next incident is prevented. After any incident that injures a staff member or involves a significant threat:

• The injured worker gets first aid or medical care, and the incident is reported following the board's procedure.
• The worker is offered support: time to recover, a check-in from the principal, and information about the employee assistance program.
• The principal investigates what happened, with the staff involved, focusing on what can be learned rather than on blame.
• The student's plan is reviewed and updated, and the people who work with the student are told about the changes.
• Serious injuries are reported to the Ministry of Labour and the WSIB as the law requires, covered in Lesson 11.
• Patterns across incidents are reviewed by the JHSC and the board.
