What Is Gaslighting?
- Manipulation that undermines your sense of reality
- The key is a pattern of repeated denial
- Respond with records, third parties, and formal channels
Once gaslighting is brought into organizational vocabulary, a dispute over 'who is right' becomes a question of 'how many times the same thing was repeated.' A single reprimand or a memory lapse is not what is being judged. The standard is whether memory denial, minimizing of feelings, and shifting of accountability have piled up on the same person over three or six months. So the unit of judgment shifts from the incident to the period, and the investigation changes too: from confronting both sides’ statements to reconstructing a chronological timeline.
In practice, sorting it into four types speeds up identification: memory manipulation that overturns facts ('I never gave that instruction'), emotional denial that belittles reactions ('If that hurts you, you can’t work here'), credit-taking that erases contributions, and isolation that cuts someone out of reporting lines and seating arrangements. What separates it from strict feedback is 'what is being denied.' Pointing out work results and behavior is feedback; denying what the other person saw and heard firsthand, and the feelings they had at the time, is manipulation. The three elements of Article 76-2 of Korea’s Labor Standards Act, namely a superior position or relationship, exceeding the appropriate scope of work, and causing physical or mental suffering, also help set the criteria for accepting a report.
The process after a report also needs to be designed differently. Gaslighting cases rarely have one decisive piece of evidence, so a single line of notes recording the time, place, and who was present is often more useful than a recording made after the fact. Upon receiving a report, the company must start an investigation without delay and separate the two parties during it. Moving the employee who reported to another team or a sidelined post is itself secondary harm. The principle is to separate them by changing the reporting line of the person named.
In practice, things go wrong in two directions. The first is the assumption that you must prove intent to harm. When an investigation asks 'Did you mean to bully them?', the answer is always 'I didn’t mean to.' The case closes, and only the person who reported is left in the organization, isolated. The standard is not intent but the effect that repeated words and actions leave behind. The other is the opposite misuse, where even a comment on a missed deadline or a low performance rating gets labeled gaslighting. After one or two such reports circulate, team leaders stop giving feedback altogether. 1:1s end with 'Nothing bothering you lately, right?', and low-performance issues all erupt at once in the year-end review. If you don’t address both boundaries together, guarding against one feeds the other.

John KimInstructor John Kim, author of B2B Marketing Design and CEO of Nanum ConsultingThe term comes from Patrick Hamilton’s 1938 play <Gas Light> and its 1944 film adaptation <Gaslight>. In the story, a husband secretly manipulates the brightness of the gas lamps while continually denying his wife’s perception, leading her to doubt herself. Psychologist Robin Stern popularized the concept in her 2007 book.
Consider a hypothetical case. At Company A, a B2B software firm with 180 employees, 3 of the 6 members of Development Team 2 left within a year. Exit interviews kept producing the line “I started to wonder if I was the problem,” so HR began looking into the cause. The remaining team members’ psychological safety score came in at 2.4 out of 5, far below the company-wide average of 4.1.
- When the HR manager reopened the exit interview records of the three people who had left, the team leader’s line 'I never gave that instruction' appeared in all three statements. The HR manager ruled out coincidence.
- Team member C, who stayed on, compiled the last six months of chat messages and meeting notes in date order and submitted them. On 11 occasions, a verbal instruction was followed on the same day by the rebuttal 'I never said that.'
- The grievance committee member interviewed the four people who had attended the meetings, one by one. Three of them independently described the same thing: the phrase “Don’t be so sensitive” being used in the weekly meeting, with matching dates.
- During the investigation, the company moved the named team leader’s reporting line, not the reporting employee’s, to the division head. The HR director made it clear: 'The person who moves is not the one who reported.'
- The team leader received a written warning, completed 8 hours of leadership training, and moved to a PM role. In a follow-up assessment six months later, Development Team 2’s psychological safety score had risen from 2.4 to 3.8, and no one else resigned.
