Use this guide if you have a problem at work, such as unfair treatment, bullying, pay issues or working conditions, that you want your employer to deal with. Have your contract, the staff handbook or grievance policy, and any notes, emails or evidence about the problem ready.
Step by step
Write down what happened
Make a dated record of each incident, including what was said or done, who was involved and any witnesses. Save relevant emails and messages somewhere you control, as long as you are allowed to keep them. Stick to facts rather than opinions.
Consider an informal approach
If you feel able to, raise the issue calmly with your manager or another suitable person, as many problems can be resolved this way. Make a note of the conversation afterwards. If the problem involves your manager, speak to their manager or HR instead.
Read your employer's grievance policy
Find the grievance procedure in your handbook or intranet, which should follow the Acas Code of Practice on disciplinary and grievance procedures. Note who to send the grievance to and any timescales. Ask HR for a copy if you cannot find it.
Write a formal grievance
Put your grievance in writing, marked as a formal grievance, and explain what happened, how it has affected you and what outcome you would like. Keep it clear and factual and attach or list your evidence. Keep a copy and note the date you sent it.
Prepare for the grievance meeting
Your employer should invite you to a meeting to discuss it. You usually have the right to be accompanied by a colleague or trade union representative. Bring your notes and evidence, and ask for a written outcome.
Appeal or get advice if unresolved
If you are unhappy with the outcome, appeal in writing following the policy. Contact Acas for free, impartial advice, as early conciliation through Acas is usually required before an employment tribunal claim. Strict time limits apply to tribunal claims, so get advice early.

Practical tips

- Keep copies of everything outside work systems in case you lose access.
Common problems
My grievance is about my own manager.
Send it to their manager or to HR, as the policy usually allows. Ask that someone independent hears the grievance. Mention this concern in your letter.
My employer has not responded to my grievance.
Send a polite follow-up referring to your original date and asking for a meeting. Keep a record of the delay. Contact Acas for advice on your options.
I am worried I will be treated badly for complaining.
Keep a careful record of any change in how you are treated after raising the grievance. Some complaints, such as those about discrimination or whistleblowing, carry legal protection. Get advice from Acas, Citizens Advice or your union.
