Dealing with toxic behaviour at work
If something at work feels wrong, it probably is.
Toxic workplaces don't just make you feel bad - they can seriously damage your mental health, career prospects, and personal life.
Millions of UK workers experience toxic workplace behaviour every year - from subtle gaslighting that makes you question your own reality, to outright bullying that leaves you dreading each workday.
Your feelings are valid.
If something feels wrong at work, it probably is. And more importantly, you don't have to suffer in silence.

Protect yourself from gaslighting, bullying and other toxic behaviour
When something bad happens at work, one of the first things you can do to protect yourself is keep notes. Making detailed notes immediately after the event happened can be important, not only for your peace of mind but if you later take your employer to tribunal.
- The date that you wrote the note
- The date that the event happened
- Who was there and where you were
- Your memory of what happened and what was said
When is toxic behaviour illegal?
UK employment law provides strong protections against toxic workplace behaviour.
Generally, toxic behaviour is illegal in UK workplaces for three reasons:
- If it’s discriminatory
- If it’s a reaction to you using a “protected” right
- If it represents a fundamental breach of contract
Real Tribunal example of toxic behaviour that is illegal
In 2021, an employee who was blind in one eye was mocked by a colleague. The colleague squinted and made funny eyes with reference to her, in order to get others at work to laugh at her.
The Tribunal found that this bullying behaviour was harassment under the Equality Act because of her disability, and awarded her £11,218.20. She also succeeded in claims for both wrongful and unfair dismissal.
