How do I report workplace bullying in the UK?
Why this matters
UK bullying claims are won and lost on documentation. Vague allegations of 'difficult behaviour' rarely succeed; specific, dated, evidenced incidents do. Many employees suffer for years without documenting — then can't prove the pattern when they finally complain. Start documenting from day one of any concerning behaviour.
Legal basis
Equality Act 2010 (harassment related to protected characteristics); Health & Safety at Work Act 1974 s.2 (employer duty for safe working environment); Protection from Harassment Act 1997 (course of conduct); Employment Rights Act 1996 (constructive dismissal s.95(1)(c)).
Step-by-step playbook
1) Document every incident immediately: date, time, location, what was said/done, witnesses, your reaction, impact. Keep this outside work systems (personal email, notebook, encrypted file). 2) Read company bullying & harassment policy — note timeframes and routes. 3) For low-level incidents, consider speaking to the person directly first (if safe) or to HR informally. 4) For serious or sustained bullying, raise a formal complaint in writing using the policy. 5) Reference the ACAS Code on grievance and (if relevant) the Equality Act. 6) Request reasonable adjustments if the bullying is affecting your health (e.g., a transfer, working from home, no contact). 7) Keep GP records of any health impact. 8) If unresolved or escalating, consider specialist employment law advice and ACAS conciliation.
Letter / template
Formal bullying complaint template: 'Dear [HR Manager], I am writing to make a formal complaint of bullying behaviour under the company's bullying and harassment policy. The complaint concerns [name and role]. The conduct includes: - [Date]: [specific incident, witnesses, evidence] - [Date]: [specific incident, witnesses, evidence] - [Date]: [specific incident, witnesses, evidence] [If applicable: I believe the conduct is also harassment under the Equality Act 2010 because it relates to my [protected characteristic — disability/race/sex/age/religion/sexual orientation].] The impact on me has been [factual impact — health, performance, attendance]. I request: - A formal investigation under the policy - Reasonable adjustments while the investigation is ongoing [specify] - The right to be accompanied at any meetings - Confidentiality Please confirm receipt and the next steps within 5 working days. Yours sincerely, [Your name]'
What NOT to do
Don't: complain verbally without follow-up in writing; rely on memory — document everything contemporaneously; share complaint details with colleagues (could become gossip and weaken the case); resign without taking advice (may give up constructive dismissal claim); confront the bully directly in escalating exchanges; ignore your health (see GP early); delete WhatsApp/email evidence.
Worked example
Tom kept a daily log of his manager's behaviour for 4 months — public criticism in meetings, exclusion from work allocation, undermining in front of clients. He filed a written complaint citing 12 specific incidents with witnesses. HR investigated, upheld the complaint, removed the manager from his line, and gave him a transfer. He kept the log throughout — without it, the complaint would have been 'his word against mine' and likely gone nowhere.
Recruiter pro tip
The most powerful tool against workplace bullying is the contemporaneous log. Update it within 24 hours of each incident. UK tribunals weight contemporaneous notes as more credible than memory months later. Use a personal notebook or encrypted file — never a work system the employer can search. The bully relies on you not documenting; documentation is the asymmetric weapon.
