What normally happens after you raise it
Most internal processes follow the same shape, because most policies are written around the Acas Code of Practice on disciplinary and grievance procedures. The Code is not law in itself, but an unreasonable failure to follow it can lead a tribunal to adjust a compensation award by up to 25 per cent.
Acknowledgement
Usually within a few days. If nothing arrives within a week, chase in writing and keep the email.
Investigation
Someone gathers documents and interviews witnesses. Ask who is investigating and whether they are independent of the people involved.
Grievance hearing
Your meeting to explain the complaint in your own words. You have a statutory right to be accompanied.
Outcome letter
The findings in writing, plus any actions. It should say whether the grievance is upheld, partly upheld, or not upheld.
Appeal
Almost always available, normally within five to ten working days of the outcome, and ideally heard by someone more senior and not previously involved.

Preparing for the grievance hearing
The hearing is not a trial and you are not there to perform. You are there to make it easy for a reasonable person to understand what happened, in order, with dates. Preparation is what makes that possible when you are nervous.
Before the hearing
- Write a one page chronology: date, what happened, who was present, and the effect on you or your work.
- Pick three to five strongest examples rather than everything. Depth beats volume.
- Say clearly what outcome you are asking for. Vague complaints get vague outcomes.
- Confirm in writing who is accompanying you, using your statutory right.
- Ask in advance for a written note of the meeting, and for a copy of the investigation findings.
- Take a bottle of water and permission to pause. You are allowed to stop and gather yourself.
Reading the outcome letter honestly
Outcome letters use careful language, and it is worth learning to read it. Look for three things: what was actually found as fact, what was found not proven and why, and what specific action follows.
- Upheld means the findings support your complaint. Ask what will change, by when, and who will confirm it.
- Partly upheld is the most common result. Ask which parts, and what happens about the rest.
- Not upheld does not mean you were disbelieved. It often means the evidence was one word against another.
- Watch for actions with no owner and no date. Training will be considered is not an outcome.
- Watch for the complaint being reframed as a personality clash or a management style issue.
You may not be told what happened to the other person. Employers usually treat that as their confidential matter. You are entitled to know what will change for you.
If your grievance is not upheld
Appeal, and appeal in writing within the deadline. An appeal is not a repeat of the grievance. It is an argument that the process or the conclusion was wrong, so ground it in specifics:
New or ignored evidence
Name the document, message or witness that was not considered, and say why it matters.
Process failures
Delay, no independent investigator, witnesses not interviewed, no note of the hearing, or being denied a companion.
Conclusions that do not follow
Where facts were accepted but the finding contradicts them.
Outcome inadequate
Where the grievance was upheld but nothing concrete was actually put in place.
Ask for the appeal to be heard by someone senior who has not been involved before. If your employer refuses, record the refusal in writing. It becomes part of the picture.
If things get worse after you complain
Retaliation is common and it is often subtle: exclusion from meetings, work being reallocated, sudden criticism of performance that was never raised before, a shift pattern changed without explanation. Treat it as a new and separate issue rather than a continuation of the old one.
Where you complained about discrimination or harassment linked to a protected characteristic, being treated badly because you complained may amount to victimisation under the Equality Act 2010. If you raised a concern in the public interest, for example about a legal breach or a health and safety danger, you may have separate whistleblowing protection.
If retaliation starts
- Log every incident with the date, who was there, and what changed compared with before.
- Put it in writing to HR, and use the word victimisation if your original complaint concerned discrimination or harassment.
- Keep copies on a personal device, not only on work systems.
- Notify Acas early conciliation so the tribunal clock is paused while you work through it.
- Get advice from a union representative, a solicitor, or Citizens Advice before resigning.
Where it can go next
Once the internal process is exhausted, the main external routes are Acas early conciliation, which is a required step before most tribunal claims and often produces a settlement on its own, and an employment tribunal claim. There is generally no fee to bring a tribunal claim.
Bullying by itself is not a standalone legal claim in Great Britain. Claims are usually framed as harassment or discrimination under the Equality Act 2010 where a protected characteristic is involved, as constructive dismissal where you resign in response to a fundamental breach, or occasionally under the Protection from Harassment Act 1997 for a course of conduct.
Not every route is worth taking, and going to a tribunal is genuinely hard on your health. It is entirely reasonable to decide that a negotiated exit, or leaving well, is the better outcome for you. That is a strategic decision, not a surrender.

Common questions
How long should a grievance take?
The Acas Code of Practice requires employers to deal with grievances promptly, without unreasonable delay. There is no fixed statutory deadline, but most internal policies aim for a hearing within about five to ten working days of the grievance being received, and a written outcome shortly afterwards.
Can I bring someone to a grievance hearing?
Yes. Under the Employment Relations Act 1999 you have a statutory right to be accompanied at a grievance hearing by a work colleague, a trade union representative, or an official employed by a trade union. Your employer's own policy may allow a wider group.
What if my grievance is not upheld?
You almost always have a right of appeal, and you should use it. Appeal in writing, within the deadline in the policy, and focus on specific grounds such as evidence that was not considered, a flawed process, or a conclusion that does not follow from the findings. Exhausting the internal process matters if you later go to a tribunal.
Is it victimisation if I am treated badly after raising a grievance?
It may be. Under the Equality Act 2010, victimisation means being subjected to a detriment because you did a protected act, such as raising a complaint of discrimination or harassment. There are also separate protections for whistleblowers. Record every incident with dates, and raise it in writing.
Can I record a grievance meeting?
Covert recording is risky and may breach your contract or your employer's policy, though tribunals have sometimes admitted such recordings. The safer route is to ask for permission, or to ask for a written note of the meeting and to submit your own corrections to it in writing afterwards.
