She asks a question in the meeting. The room answers to someone else, and the decision is minuted under another name. Two colleagues copied on her email reply to each other instead of to her. Nothing shouted, nothing written down, and she spends the evening rehearsing what she did wrong.
What is covert bullying, and why is it so hard to name?
Covert bullying is repeated, targeted hostility delivered through indirect means — exclusion, withheld information, rumour, stolen credit — so the act cannot be named or contested. It hurts more than shouting because shouting is visible and attributable, while covert tactics leave the target doubting that anything happened.
In isolation, each event has an innocent explanation, and that is the design. The target assembles a pattern that no single incident confirms. Self-doubt follows rather than anger: the person searches their own conduct for the fault, because fault is the only variable still available to them.
In my own practice the person who is being covertly bullied rarely arrives saying so. She arrives with insomnia, a tight jaw and the sentence ‘maybe I am just too sensitive’; only weeks later does the pattern of missing invitations, stolen credit and information that reaches her last come into focus.

What does covert bullying do to mental health?
Covert bullying is associated with serious mental-health outcomes, including suicidal thinking and increased alcohol use, in large samples of working adults.
Luo and colleagues, 2023, reviewed 25 articles and pooled 15. In the pooled samples, 18% reported suicidal ideation and 4% reported suicidal behaviour; those percentages describe those pooled samples only. Workers exposed to workplace bullying had 2.03 times higher odds of suicidal ideation and 2.67 times higher odds of suicidal behaviour after adjustment for confounders. Most of the data are cross-sectional and heterogeneity between studies is substantial.
[Further verification needed: whether the 18% and 4% prevalence figures in the 2023 meta-analysis refer to bullied workers only or to the whole pooled samples.]
Xu and colleagues, 2026, followed 4 cohorts in Sweden, Denmark, Finland and Norway, 78,624 participants aged 18 to 65, with baselines from 2004 to 2016. Over 1 to 2 years, 6 to 8% of these participants experienced onset of workplace bullying. Onset was associated with starting excessive alcohol use, odds ratio 1.23 (95% confidence interval 1.06 to 1.44) in the concurrent analysis, weaker in the longitudinal analysis. The samples are Nordic workforces and the design is observational.
Does changing jobs solve it?
Changing jobs reduces exposure to bullying and appears to relieve anxiety, but it does not reliably relieve depression. Longitudinal Swedish evidence shows two different outcomes from the same move, which matters for what targets, employers and clinicians expect from leaving.
Rosander, Salin and Blomberg, 2022, followed a probability sample of 1,095 Swedish employees for 18 months. Employees bullied at baseline were more likely to have changed jobs. Those who changed jobs showed a substantial drop in exposure to bullying, and for them the link between bullying and later anxiety was no longer significant. Depression did not move in the same way: the association between bullying and later depression was the same 18 months later. One country, self-report, 18 months only.
Rosander, 2021, using another Swedish longitudinal probability sample, reported that prior mental-health problems raised the risk of being bullied later only where the organisation lacked role clarity and order, with going to work while sick partly explaining that path. Questionnaire data, one country.
My position is clear: covert bullying is a disease of the organisation, not a clash of two personalities, and the data on job change show why treating only the target leaves the structure that produced the bullying intact.

What should the target do, and what should the leader do?
The target should document and protect, and the leader should remove the ambiguity that lets covert tactics survive. Recording events is the first step because covert bullying is defined by deniability, and role clarity is the organisational lever with the strongest supporting evidence.
For the target, the practical work is documentation. Keep a dated written record: what was said, who was present, and what it cost in task terms. Report calmly and factually, in writing where possible, and describe the effect on the work rather than the character of the colleague. Expect retaliation and keep a copy of the record outside the workplace. Sleep and relationships outside the job need active protection; they carry the load.
For the leader, the sequence is different. Define who decides what, publish it and apply it consistently, because role clarity and order are where vulnerability either becomes bullying or does not. Act on the first signs, before the pattern is complete.
How is covert bullying different from ordinary conflict at work?
Ordinary conflict is usually visible, mutual and about a specific disagreement: two people want different things and both know it. Covert bullying is one-directional, repeated and designed to stay deniable. The target is excluded, misinformed or stripped of credit while no single incident looks like aggression, which makes it harder to report and harder to resolve.
Does leaving the job repair the damage?
Partly. In the Swedish sample of 1,095 employees followed for 18 months, those who changed jobs had a substantial drop in exposure and their later anxiety was no longer significantly linked to bullying. Depression symptoms were unchanged, and the link between bullying and later depression held at 18 months.
Can a person’s own mental health make them a target?
Prior mental-health problems raised the risk of later bullying in Swedish questionnaire data only when the organisation lacked role clarity and order, and attending work while sick partly explained that path. Vulnerability matters, but it matters through organisational conditions. The same person in an ordered workplace with clear roles is not automatically at higher risk.
What is the first practical step for someone who suspects they are being bullied?
Start a dated written record. Note each incident, who was present, what information arrived late or not at all, and what it cost in task terms. Facts recorded close to the event are more useful than a later narrative. Then report calmly and factually in writing, and keep a copy outside the workplace.
Conclusion
Covert bullying is deniable by design, and it leaves a measurable mark. Luo and colleagues, 2023, pooled 15 articles and found that 18% of the pooled samples reported suicidal ideation and 4% reported suicidal behaviour, with exposed workers showing 2.03 times higher odds of ideation and 2.67 times higher odds of behaviour. Xu and colleagues, 2026, found onset of bullying in 6 to 8% of 78,624 Nordic participants over 1 to 2 years. Changing jobs relieved anxiety in the Swedish sample of 1,095 employees but left depression unchanged 18 months later. The conditions that produce covert bullying can be changed.
