A physically small child with a bent paperclip attached and threatened worker - so why did his trauma claim collapse?
A behavioural specialist was punched, kicked, chased and received death threats from a child he worked with, yet Alberta's workers' compensation appeal body decided he did not have an acceptable claim for traumatic onset psychological injury. In a ruling dated May 14, 2026, a panel led by Hearing Chair J. Keil found the incident fell within the ordinary risks of his job.
The worker was an emotional behavioural specialist who provided crisis intervention for children with severe behavioural and emotional challenges. In March 2023, he was working with a group of youths when an elementary school-aged child ran into the room and attacked him, swinging fists and yelling threats.
A co-worker cleared the other children and went for help, leaving the worker alone with the child for six to seven minutes. The child kept swinging and kicking, so the worker twice held the child to the ground using a restrictive procedure. The child tried to bite him, threw furniture, and at one point gripped a bent paperclip the worker took away.
The only physical harm to the worker was a bruised elbow. The Workers’ Compensation Board (WCB) accepted a claim for an elbow contusion and an acute reaction to stress in April 2023, and the worker's psychologist later diagnosed an adjustment disorder with mixed anxiety and mood. He received wage-loss benefits and began a gradual return to work before WCB, in a September 6, 2023, letter, said he had recovered successfully in August and inactivated the claim.
When the danger is part of the job
To count as a compensable traumatic event under Alberta's policy, an incident must clear four tests: sudden and unexpected; frightening or shocking; tied to a specific time and place; and involving actual or threatened death, serious injury, or a threat to physical integrity. The panel agreed two were met: it was sudden, unexpected, and clearly located.
The other two were the problem. The panel found the event was not frightening or shocking because, reasonably assessed, it sat within what the man's role already demanded. He had worked with this child for years, had helped shape the strategies for managing the child's behaviour, and had been asked to avoid engaging with the child after being flagged as a trigger. The child was about 10 and physically small, the alleged weapon was a paperclip, and the worker was a 42-year-old trained in crisis intervention.
The threats did not change the outcome. The child repeatedly yelled, "I'm going to kill you, you took my scissors, my mom told me," but the panel found the worker stayed in physical control throughout, and that verbal threats alone did not meet the severity the policy requires. The attack was significant to the worker, the panel said, but significance alone was not the test.
What it signals for high-risk workplaces
The result reversed an earlier decision in the worker's favour. The appeal was allowed on all three issues, so he has no acceptable claim for a traumatic onset psychological injury and is not entitled to the temporary disability benefits previously awarded. His elbow contusion stayed a valid claim, but because it did not restrict his ability to work, it carried no wage-loss benefits.
The panel was careful to add that a worker attacked by a client with known violent behaviours can still have a valid claim. It pointed to factors like physical size, strength, and a weapon that could make such an event frightening when reasonably assessed. Those factors, it found, were not present here.
What carried the decision was context: the worker's job duties, training, and long familiarity with the child weighed against the event's actual severity. His own incident report mattered most, including his account of the bruised elbow as "so insignificant that he was surprised it had been reported."
