Bullying Trauma in Adults: How School and Workplace Bullying Leave a Mark

Some people can still describe the exact corridor, the canteen table or the meeting room where it happened. Others cannot recall a single scene, only a lasting sense that groups are unsafe and that being noticed leads to being humiliated. The mind often keeps the feeling long after it has let go of the details.

Bullying is usually discussed as a problem of childhood, yet research that follows bullied children into adulthood, together with studies of employees bullied at work, shows effects that can reach well into later life. The reactions that follow are common and understandable. They are not a sign of weakness, and they are not an overreaction to the past.

What Bullying Trauma Means

Bullying is repeated, hostile behaviour directed at a person who finds it hard to stop it, usually because the other person or group has more power, status or social backing. The harm comes from repetition and helplessness as much as from any single incident. Trauma is the lasting psychological response to experiences that overwhelm a person's capacity to cope, and prolonged humiliation, exclusion or intimidation can do exactly that.

A meta-analysis of 29 cross-sectional studies, covering bullying at school and at work, found that on average 57 per cent of bullied people reported post-traumatic stress symptoms above clinical thresholds, and bullying was clearly associated with higher symptom scores (Nielsen et al., 2015). The studies relied on questionnaires and not on diagnostic interviews, so the findings do not show how many bullied people would meet the full criteria for post-traumatic stress disorder (Nielsen et al., 2015). Not everyone who is bullied develops trauma symptoms, but many do, and the experience deserves to be taken seriously even when it never involved physical harm.

Bullying Versus Ordinary Conflict

Disagreement, a demanding manager or a personality clash is not bullying in itself. The two usually differ in several consistent ways:

School and work settings can blur these lines, which is part of why many people spend years unsure whether what happened "counts".

School and Workplace Bullying in Singapore

Bullying in School

School bullying takes several forms: physical aggression, name-calling, deliberate exclusion, rumours and, increasingly, online harassment. A study of 3,319 adolescents aged 12 to 17 in Singapore found that traditional bullying victimisation was more common than cybervictimisation, that the two overlapped substantially, and that adolescents bullied in both ways reported the most emotional difficulties (Khong et al., 2020). For many young people, then, the harassment can follow them home through phones and group chats, with no clear end to the school day.

Local school life can add its own pressures. Academic comparison, tightly knit class and co-curricular groups, and an emphasis on keeping up appearances can make it harder for a young person to tell an adult, and harder for adults to take exclusion or teasing seriously. In clinical experience, many adults who were bullied in these settings describe having concluded at the time that the problem was something wrong with them, a belief that tends to travel into adulthood largely unchanged.

Bullying at Work

Workplace bullying tends to be less overt than the school version. Common forms include persistent criticism out of proportion to the work, exclusion from meetings and information, unmanageable workloads, public humiliation and rumours passed among colleagues. Because each incident can be defended as a management decision or a joke, the pattern is often visible only to the person living it.

Hierarchy, fear of a poor appraisal and an expectation of enduring pressure can discourage people in Singapore from naming what is happening. The stakes can feel higher still for those whose work passes are tied to a single employer. Prolonged bullying can also overlap with exhaustion and burnout, a connection covered in our guide to stress and burnout in Singapore.

How Bullying Affects Adults Years Later

Mental Health

Research that follows bullied children into adulthood links being bullied with higher rates of anxiety, depression and suicidal thoughts (Wolke & Lereya, 2015). In two cohorts, one British and one American, children bullied by peers had higher odds of anxiety, depression and self-harm or suicidal thoughts in adulthood (Lereya et al., 2015). A major review of the evidence found that the effects of being bullied persist into adulthood, and that they were still evident at age 50 in a British cohort (Arseneault, 2018).

The same pattern appears for adults bullied at work. A meta-analysis found that workplace bullying was associated with depression, anxiety and stress-related complaints, and that being bullied predicted later mental health problems over time (Verkuil et al., 2015). The analysis also found that existing mental health difficulties predicted later bullying, although that finding rests on fewer studies and on self-reported data (Verkuil et al., 2015). Distress and bullying can therefore feed each other, which is not evidence that anyone is responsible for being targeted.

Thoughts of self-harm or suicide are among the documented outcomes, and they deserve to be taken seriously and not treated as a sign of weakness. If you are in immediate danger, call 995 or see our emergency resources.

Relationships and Trust

Adults who were bullied in childhood report more difficulty forming friendships and partnerships, and in getting social support (Arseneault, 2018; Wolke & Lereya, 2015). The mechanism is rarely mysterious. A person who learned that closeness could be used against them often becomes quick to anticipate rejection, reads neutral tones as criticism and withdraws before anyone can exclude them.

Others do the opposite and work hard to be agreeable so that nobody has a reason to turn on them. When the fear hardens into dread of social situations, it overlaps with what is described on the social anxiety page, and you can learn more about the isolation that can follow on the loneliness page.

Work and Earnings

Bullying can also leave a mark on working life. A study following a British cohort found that, at around age 50, adults who had been bullied as children were less often in paid work and had fewer assets such as homes or savings, and bullied women earned less (Brimblecombe et al., 2018). Reviews of the wider evidence similarly link childhood victimisation with lower educational attainment and less stable employment (Wolke & Lereya, 2015). These are group averages, and they do not predict the path of any individual.

Physical Health

Bodily effects are part of the picture as well. People bullied in childhood report more bodily pain and headaches and slower recovery from illness in adulthood (Wolke & Lereya, 2015). Persistent physical symptoms should be assessed by a doctor, because they can have causes unrelated to the past.

How Bullying Trauma Appears in Daily Life

The aftermath tends to appear less as dramatic flashbacks and more as habits of mind and body that once offered protection. Many people recognise several of the following patterns, and some recognise only a few.

Shame and Self-Blame

Many people who were bullied conclude, at the time, that they must have deserved it. That conclusion often outlasts the bullying by decades and shows up as harsh self-criticism, a sense of being fundamentally unlikeable or discomfort when praised. For a closer look at these feelings, see the pages on shame and guilt and self-criticism.

Hypervigilance and Social Scanning

Someone who was targeted in a group may keep scanning rooms for signs of hostility: who is whispering, who has not replied, whether a tone has changed. The scanning is tiring and usually invisible to others. It tends to flare in group chats, open-plan offices, social events and performance reviews.

Over-Adapting and People-Pleasing

Some people learned that agreeableness reduced the risk of being targeted. In adult life this can look like struggling to say no, apologising for taking up space or taking on extra work to avoid conflict. Difficulty with limits is explored on the boundaries and assertiveness page.

Reactions to Authority and Groups

Criticism from a manager can feel out of proportion to its content, and being left out of a message thread can produce a surge of old feelings. Some people avoid visibility at work altogether and turn down promotions or presentations that would draw attention. Others become intensely defensive. These responses make sense as learned protection that is still running after the danger has passed.

Withdrawal and Avoidance

Avoidance can be gradual: skipping reunions, leaving group chats, declining invitations, working from home whenever possible. For some young people, withdrawal after bullying becomes severe and prolonged, a pattern described in our article on hikikomori among youth in Singapore.

Why Old Bullying Resurfaces

Old bullying often returns when life repeats part of it. Common triggers include joining a workplace with a similar dynamic, a child reaching the age at which the person was bullied, a school reunion, an online reminder, or news that the person who bullied them is thriving. A strong reaction in these moments is not a setback. It can be a sign that the experience was never fully processed.

Common Misconceptions About Bullying

What Can Help in Recovery

Naming What Happened

Writing a plain, factual account of what occurred, including dates, places and the words used, can turn a vague burden into something with edges. Many people find it useful to add what they believed about themselves at the time, and then ask whether a different reading is possible, as they would for a friend telling the same story. Keep the account somewhere private.

Separating Then From Now

When an old reaction surges, it helps to pause and orient to the present: say the date and where you are, notice five things in the room and let each out-breath run longer than the in-breath. The aim is not to argue the feeling away but to show the body that the situation has changed. Many people find this works better when practised on ordinary days than only in a crisis.

Rebuilding Trust in Small Steps

Trust tends to rebuild through repeated low-stakes experiences with people who are consistent, such as a colleague who follows through or a friend who responds kindly to a small disclosure. Sharing a little more only when the response is steady lets a person test safety without risking everything at once. Clubs, classes and interest groups can offer structured contact that asks less than open social settings.

Dealing With Workplace Bullying Now

If bullying is happening currently, practical steps matter as much as emotional ones. Keep your own dated notes of incidents, including what was said or done and who was present, and avoid copying confidential company documents. Check the organisation's grievance or anti-harassment policy before deciding what to do.

The Tripartite Alliance for Fair and Progressive Employment Practices (TAFEP) advises employees who experience workplace harassment, including on internal grievance procedures and other options, and its page on seeking help with workplace harassment explains the routes available. Leaving a harmful workplace is also a legitimate choice and not a failure. For the emotional side of work difficulties, see our page on workplace issues.

When to Seek Professional Support

Some after-effects ease with time and with support from people nearby. Professional help is worth considering when symptoms last for weeks, interfere with work or relationships, or feel too heavy to manage alone. Common signs include:

• Intrusive memories or nightmares

• Panic when reminded of the past

• Avoiding people and places until life becomes smaller

• Persistent low mood or loss of interest

• Thoughts of self-harm

Whether symptoms amount to post-traumatic stress disorder or another condition can only be decided through assessment by a qualified clinician. Repeated experiences that a person could not escape, especially where people or institutions failed to protect them, can produce patterns that go beyond a single-event picture, and we explore this in more detail in complex trauma and C-PTSD in Singapore. How support for trauma-related symptoms works is described under trauma and PTSD counselling.

Frequently Asked Questions

What Changes When It Is Named

Naming bullying as bullying, and its effects as effects, tends to change the question a person asks. "What is wrong with me?" becomes "What happened to me, and what did it teach me to expect?"

That question has answers, and they point towards change. The patterns that formed to survive hostile settings can be understood, and many people find that they loosen once they are no longer mistaken for character.
