A worker is filling in intake paperwork for someone who moved in last week. There is a box headed "relevant background" and the last service left it blank. A team leader says to fill in what can be found. The instinct is to ask gently over a cup of tea, so the person can say as much or as little as they like. It feels kind. It is also, still, a worker asking someone to account for themselves in their first week, and it is exactly the kind of moment this condition asks a worker to think differently about.
Most people who go through a traumatic event do not develop PTSD, and most of the time, with most people, a shift is an ordinary shift. PTSD is treatable and complex trauma is workable, and people do live well with it. The person has usually lived with this for years and knows more about it than a worker does. Using the words someone uses about themselves, and asking if you are not sure, is the first behaviour worth carrying onto a shift.
Some of what follows may land close to home for some readers. That is ordinary in this line of work. Stop if you need to, and talk to someone. Lifeline is on 13 11 14, any time, and 13YARN is on 13 92 76, any time, for Aboriginal and Torres Strait Islander people.
What is the difference between PTSD and complex trauma?
PTSD is more often about an event. Complex trauma is more often about a life, following harm that happened inside a relationship the person could not leave. It can shape how feelings arrive (fast, hard, and slow to settle, or sometimes nothing registering at all), how a person sees themselves (a settled belief of being worthless, or to blame), and how easily a person can trust or stay close to others.
The two big classification manuals disagree about whether complex trauma is its own diagnosis. The World Health Organization's ICD-11 lists Complex PTSD as a sibling diagnosis to PTSD, asking for everything PTSD asks for plus three more things: emotions that are hard to regulate, a settled belief of being worthless, and difficulty staying close to anyone. The American DSM-5-TR has no separate category at all, and records the same features as PTSD. Australia has not moved to ICD-11: our health records still use ICD-10-AM, which has no code for Complex PTSD. A person can hold a diagnosis the system cannot record, and that is not a worker's to settle. It does not change what they need.
What does it actually look like on shift?
Four things show up, and they do not arrive tidily or all at once in the same person. A memory can arrive without being called, so a song or a smell changes the whole day. A person might steer away from anything connected to what happened, cancel the same appointment again, or refuse to use a particular room. Threat detection can stay turned up, so someone sits with their back to the wall, faces the door, or startles and then apologises for it. And some people go blank mid-conversation: detached, staring, losing the thread, needing you to repeat the last thing you said.
That last one, dissociation, is often misread as ignoring someone, being rude, or lying. It is involuntary, and it is often what a body learned to do when there was genuinely no way out. Pressing harder for a response raises distress, which deepens the shutdown, and the deepening then gets read as proof the person was never listening in the first place. The better response is fewer words, more space, no demands, and physical safety while you wait.
Should a worker ask about someone's trauma history?
No, and this holds even for a worker who understands the condition well. Knowing what intrusion and avoidance are does not change the rule: a worker never asks a person for their trauma story and never makes the trauma the subject, whether for a file, a plan, a risk assessment or a handover, and never asks a family member for it either. The reason is not squeamishness. Recounting a traumatic memory without clinical support can put a person back into it.
If someone chooses to tell you something, receive it. Do not push for detail, do not ask the next question, and let the person lead and let them stop. Knowing more about trauma is not, on its own, a reason to go looking for it.
Why does a worker's note matter so much here?
Twelve words get used in this sector that do real damage and belong nowhere in a note: non-compliant, refused, declined to engage, resistant, not motivated, attention-seeking, manipulative, difficult, paranoid, dramatic, playing up, and kicked off. A trauma response recorded as a behaviour of concern tends to get a behavioural answer: a strategy, a consequence, a restriction, when what actually happened was protective, not chosen to achieve anything.
Write what you saw, what was said in the person's own words, what you did, and who you told. Nothing else. That factual record, especially the thirty minutes before a response, is often the only evidence a behaviour support practitioner or clinician ever gets, and it travels into handover, the next provider's intake, hospital triage, and the evidence used at a plan reassessment.
Why does the same word mean something different for Aboriginal and Torres Strait Islander people?
Aboriginal and Torres Strait Islander people often do not use the words "mental health" at all. The term is social and emotional wellbeing, and it is not a softer version of the same idea. It holds a person's wellbeing across several connections: to body, mind and emotions; to family and kinship; to community; and to culture, Country, spirituality and ancestors. A change can sit in one of those connections rather than in anything that looks like a symptom, and a person cut off from family or unable to get to Country can show real distress that no symptom checklist will explain. There is no single Aboriginal or Torres Strait Islander culture, and what is true for one person may not be true for the next. Ask what wellbeing means to this person, and record their own words, not a worker's.
Who is most likely to be missed?
People with intellectual disability are harmed at high rates and are under-diagnosed, partly because standard assessments assume a spoken account and partly because distress in this group too often goes to behaviour support rather than to a clinician. Trauma without words can arrive as a refusal, or a body going still, and a worker's factual note may be the only evidence that exists. The reverse mistake also happens: once a label like "trauma" or "disability" is attached, everything else stops getting looked at. Check the ordinary explanation first, every time: pain, an infection, constipation, a sore tooth, a medication effect, hunger, tiredness, or bad news. The person can also just be right.
National survey data gives a sense of scale. In one year, an estimated 11.4 per cent of Australian adults with disability experienced abuse or neglect, rising to around 20.4 per cent for psychosocial disability and 16.5 per cent for difficulty learning or understanding, against 5.5 per cent of people with disability and 2.8 per cent of people without disability reporting assault or threatened assault. These are survey estimates, and the real rates are almost certainly higher. The Disability Royal Commission found harm in group homes, hospitals, schools and respite, much of it by people who believed they were helping.
Why might someone treat a support worker as a risk?
Much of what this workforce meets was caused, at some point, by services: placements changed with no say, no lock on a door, personal care done to someone rather than with them. A paid worker, in a person's home, with keys, doing personal care, who changes every roster, is structurally close to the thing that caused the original harm for many people. A wary or testing response to a new worker is accurate to that history, not a judgement about the worker's character, and it is not a compliment when it eventually goes well either. Withdrawing warmth after being met with suspicion is one of the most common informal punishments in this sector, and it lands as exactly the confirmation the person was braced for.
When does this go beyond what a support worker can manage?
Being held down, shut in, or medicated to settle someone down repeats, for many people, something that already happened to them, and it tends to make the original response worse rather than better, which then reads to staff in the room as proof the restriction was needed. That is a mechanism that catches good teams, not a story about bad workers, and it is why some of the most ordinary-sounding practices deserve a second look: being sent to a room while a worker stands at the door, a sensory room the person cannot freely leave, a door held shut from outside, or being kept in a bedroom during handover. Each of these is seclusion, whatever it is called, and the name does not change what it is.
Medication prescribed by a doctor to treat a diagnosed condition, and given for that purpose, is treatment, not restraint. A worker never decides which one applies: notice, record and report. Seclusion is one of five regulated restrictive practices under the NDIS rules, alongside chemical, mechanical, physical and environmental restraint, and none of the five needs a lock or a bad intention to count. And repeated exposure to other people's distress has real effects on a worker too, lying awake about someone, dreams about work, feeling flat, catching yourself using the words on the banned list above. That is not a sign of weakness, and it is not fixed by individual resilience. It goes to supervision and your organisation's EAP.
Who does a worker ring, and in what order?
Ring 000 first, always, for a life-threatening emergency. Then the organisation's own policy and escalation contact, and the named clinical contact in the person's plan. Poisons Information on 13 11 26 covers anything taken, with 000 as well if the person is unwell. Healthdirect on 1800 022 222 is there for health advice that is not an emergency. Lifeline and 13YARN are for the person, not an escalation. A restriction a worker has recognised goes into the organisation's incident process in writing, the same shift. Raising it is not disloyalty. It is the obligation.
The line worth holding
You do not need the story. You never needed the story. What a clinician needs is a record of what actually happened, and you are often the only person in the room who can write it. Recognising a trauma response, writing a factual note, and recognising seclusion by another name are squarely within a support worker's role. Exploring someone's history, or deciding what their response means, is not.
How CORA's course fits into this
CORA's course Understanding: PTSD and Complex Trauma, part of the Mental Health & Wellbeing stream in the course library, covers what PTSD and complex trauma are, what they get mistaken for, and what to do when the help being offered risks becoming harm, including restrictive practices and the worker's own exposure to repeated distress. It builds understanding and judgement. It is not clinical training, it is not a substitute for treatment, and CORA does not certify a worker's competence, that assessment sits with your organisation.
If you are mapping this alongside the rest of the Mental Health & Wellbeing stream for your whole team, the Free tools page has a free tool that maps it out, no sign-up required. Or enquire if you would rather talk it through.

Should a support worker ask someone about their trauma history?
No. A worker never asks a person for their trauma story and never makes the trauma the subject, even if the worker understands the condition well. Recounting a traumatic memory without clinical support can put a person back into it. If someone chooses to tell you something, receive it without pushing for detail, and let them lead and let them stop.
Why does someone go blank or stop responding mid-conversation?
This is dissociation, a form of detachment that sits on a range from a brief absence to missing time. It is not ignoring you, being rude, or lying, and it is involuntary. Pressing harder for a response raises distress, which tends to deepen it, so the better move is fewer words, more space, no demands, and waiting until the person comes back in their own time.
Why might someone with PTSD or complex trauma be guarded around a new support worker?
A paid worker who has keys, does personal care, and changes every roster is structurally close to the kind of relationship that caused the original harm for many people. A wary or testing response is accurate to that history, not a judgement about the worker's character, and it is not a compliment when it eventually goes well either. Turning up consistently, doing what you said you would, and letting time do the rest is the actual work.
Can a support worker diagnose PTSD or provide trauma-informed therapy?
No. Recognising what you are seeing, writing a factual record, and reporting changes is within a support worker's role. Diagnosis and treatment sit with GPs and mental health professionals. A worker's record of what happened before a response, in plain factual terms, is often the only evidence that exists for a clinician to act on.
