How to recognise & respond to gaslighting at work

Gaslighting at work can be hard to name at first. It often starts with small moments that seem confusing rather than clearly harmful.

A colleague insists they sent you information you never received. A manager changes an instruction, then criticises you for following the original one. You raise a concern and get told you’re “too sensitive”, “dramatic”, or “difficult”. After a while, you may start checking emails over and over, apologising for things that weren’t your fault, or feeling anxious before ordinary meetings.

Workplace gaslighting is more than a disagreement or a difficult personality clash. It’s a pattern that can undermine your sense of reality, your professional confidence, and your mental health. In a toxic workplace, it may sit alongside gossip, exclusion, inconsistent expectations, and poor leadership. Left unchecked, it can increase your stress levels and damage your sense of psychosocial safety.

What is workplace gaslighting?

Gaslighting is a form of psychological manipulation where someone causes you to question your memory, judgement, perception, or emotional response. In workplaces, it usually happens through repeated behaviours rather than one obvious incident.

Gaslighting at work can involve a manager, colleague, senior leader, client, or several people acting in similar ways. It may include repeatedly denying an instruction, agreement, or conversation, or questioning your reliability, competence, or emotional response in a way that undermines your credibility.

Workplace gaslighting often involves power. That power may be formal, such as a manager controlling your workload or performance review. It may also be social, such as a well-liked colleague influencing how others see you.

The key pattern is distortion. You’re left trying to prove what happened, explain your intentions, or defend your competence, while the other person avoids accountability.

Signs of gaslighting in the workplace

Gaslighting can look different depending on the person, the team, and the power dynamics involved. Still, there are several signs that tend to appear often.

1. They deny conversations or agreements

You may clearly remember a conversation, but the other person insists it never happened. They might say, “I never told you that,” “You’ve misunderstood,” or “That’s not what we agreed on.”

This becomes especially harmful when important instructions are given verbally, then later denied. You may be blamed for missing a deadline, following the wrong process, or failing to meet expectations that were never actually set.

2. They keep changing expectations

A manager or colleague may move the goalposts. You complete a task as requested, then they say the priority was something else. Feedback may shift from one week to the next, leaving you unsure what “good work” actually looks like.

3. They minimise your concerns

A common sign of workplace gaslighting is being told your reaction is the problem. You may hear comments like, “You’re overreacting,” “No one else has an issue,” or “You always take things personally.”

This kind of response turns attention away from the behaviour you raised. Instead of addressing the concern, the person questions your emotional stability, professionalism, or judgement.

4. They withhold information, then blame you

Some gaslighting happens through omission. You might be left out of meetings, removed from email chains, or not told about changes to a project. When something goes wrong, you’re blamed for being unprepared or disorganised.

Over time, this can affect your performance record, reputation, and confidence, even when the real issue is that you weren’t given the information needed to do your job well.

5. They use gossip to damage your credibility

Gossip in the workplace can become part of a gaslighting pattern when it’s used to isolate you or shape how others interpret your behaviour. For example, someone may tell colleagues that you’re “unstable”, “negative”, or “not coping”, especially after you’ve raised a concern.

This can leave you feeling watched, judged, or unsure who to trust. It can also make it harder to speak up because you fear your words will be twisted.

6. You notice the impact on your wellbeing

Gaslighting often shows up in your body and behaviour before you have the words for it. You may feel tense before speaking to a particular person, replay conversations after work, second-guess simple decisions, or start collecting proof for interactions that used to feel straightforward.

These micro-stressors can build slowly. A dismissive comment here, a denied conversation there, a changed expectation the next week. Each moment may seem small, but the ongoing pressure can wear down your mental health.

Why gaslighting is a workplace wellbeing issue

Gaslighting affects more than confidence. It can influence how safe you feel at work, how well you can focus, and how much energy you have left at the end of the day.

When your reality is repeatedly questioned, your nervous system may stay on alert. You may become hypervigilant, scanning for mistakes, saving every message, or rehearsing conversations before they happen. Work can start to feel unpredictable and unsafe.

This matters for employers, too. A workplace that tolerates gaslighting, bullying, and gossip often sees lower trust, poorer collaboration, and higher turnover. Employee retention suffers when people feel they have to protect themselves from the culture rather than contribute to it.

Psychosocial safety needs consistent leadership, just systems, and respectful communication. Training helps, but it cannot replace action when harmful behaviour is reported.

How to respond to gaslighting at work

Responding to workplace gaslighting takes care and planning. You may be dealing with someone who has more authority, more social influence, or a history of shifting blame. Your first step is to protect your wellbeing and create a clearer record of what’s happening.

1. Write down what happened

Keep notes that are factual, dated, and specific. Include what was said, who was present, what changed, and how it affected your work. Save relevant emails, messages, meeting notes, rosters, performance documents, or project updates.

Try to record exact wording where you can. A note like “Manager said I was ‘too emotional’ after I asked for the project brief in writing” is more useful than “Manager was horrible again.”

2. Put important instructions in writing

Gaslighting thrives when everything is verbal and unclear. After meetings or calls, send a brief follow-up message confirming what was agreed.

For example: “Thanks for meeting today. My understanding is that the client report is now the priority, the internal update can wait until Friday, and the deadline for the draft has moved to Wednesday. Please let me know if I’ve missed anything.”

This gives everyone a chance to clarify expectations and gives you a written record if the story changes later.

3. Speak to someone you trust

Choose someone calm and appropriate. This could be a trusted manager, mentor, HR contact, union representative, health and safety representative, counsellor, psychologist, or EAP clinician.

You don’t need to prove the whole pattern in one conversation. Start with the facts and the impact: what has happened, how often it has happened, and how it’s affecting your work or wellbeing.

4. Use clear, behaviour-based language

It’s usually safer and more effective to describe the conduct rather than label the person. Instead of saying, “They’re a gaslighter,” you might say: “I’m concerned that instructions are being changed after the fact, and I’m then being criticised for not following the new version.”

This keeps the focus on observable behaviour, which is easier for HR or managers to assess.

5. Set boundaries where it’s safe

If the situation allows, use calm and direct boundaries. You might say, “I’m happy to discuss feedback, but I need specific examples,” or “I’d prefer project changes to be confirmed in writing so I can keep track.”

If there is a power imbalance, or if you’re worried about retaliation, it might be better to seek advice before confronting the person directly.

6. Look after your health

Gaslighting can be exhausting. It can affect your sleep, mood, concentration, confidence, and even your sense of identity outside of work. Counselling or psychological support can help you sort through what’s happening, manage stress, and decide on practical next steps.

You don’t have to wait until you’re burnt out to speak with a professional. Early support can help you stay grounded while you consider your options.

How employee wellbeing services can help

Employee wellbeing resources, including an Employee Assistance Program, can play an important role when workplace gaslighting is affecting your mental health.An EAP won’t investigate a complaint, act as your lawyer, or replace HR, but it can give you a confidential space to talk through the situation with a qualified professional. That support can help you organise your thoughts, prepare for a difficult conversation, understand your stress response, and work out what you need to feel safer.

Talked’s employee wellbeing services give employees access to psychologists, counsellors, mental health nurses, and broader wellbeing support. For someone dealing with toxic workplace patterns, this kind of support can be a practical starting point. You can speak with someone outside the workplace who is trained to listen, ask useful questions, and help you plan.

EAP support may also help you prepare notes before speaking to HR, practise boundary-setting, manage anxiety before work, or process the emotional impact of being repeatedly dismissed or blamed.

A note for managers and employers

Managers and employers need to take reports of gaslighting, bullying, and psychosocial hazards seriously. When an employee says they feel undermined, blamed, excluded, or repeatedly dismissed, don’t reduce it to a personality clash. Look at the behaviour, the pattern, the power dynamics, and the impact on the person’s work and wellbeing.

Gaslighting is more likely to take hold in workplaces with poor work clarity, inconsistent communication, and weak accountability. Practical prevention includes training managers in psychosocial risk, setting clear expectations, addressing harmful behaviour early, documenting performance concerns fairly, protecting employees from retaliation, and making reporting pathways easy to understand.

Employee wellbeing resources should also be visible, accessible, and normalised before people reach crisis point. If you don’t have an EAP in place, or you’re considering switching EAP providers, Talked’s pay-as-you-go EAP can help you provide a flexible way to offer counselling or psychology support. You may book a demo with Talked to explore how its employee wellbeing services can support your team.

Final thoughts

Gaslighting at work can leave you doubting your judgement, replaying conversations, and feeling anxious in a role you once handled with confidence. The behaviour may be subtle, but the impact can be serious.

Start with facts. Keep records, confirm instructions in writing, and speak with someone trustworthy. If your mental health is being affected, counselling or psychology support can help you steady yourself and plan your next step.

A therapist or EAP clinician can give you space to unpack what has happened without judgement. With the right support, you can make decisions from a place of greater confidence, care, and self-trust.
