What to do if…
you are told a colleague has made a formal complaint about you

Short answer

Do not contact the coworker who complained. Ask HR for the allegation and the investigation process in writing, and get appropriate support (union representation if applicable, or a permitted support person) before you give a detailed response.

Do not do these things

Do not confront, message, “apologize to,” or try to negotiate directly with the coworker who complained.
Do not ask coworkers to “take sides,” compare stories, or pressure the complainant or witnesses.
Do not delete or change messages, files, calendar events, or notes that could be relevant.
Do not post about it on social media or discuss it in workplace group chats.
Do not make threats, jokes, or “off-the-record” comments—those are commonly repeated and documented.
Do not record meetings unless you have clear permission and it complies with company policy and applicable law. If you want a record, ask HR for written notes/minutes.

What to do now

Get the basics in writing (today). Ask HR for:
- the policy/process being used (harassment policy, conduct policy, investigation policy, union contract process, etc.)
- what the complaint generally alleges (topics and timeframe)
- what HR needs from you next (interview, written statement, names of witnesses)
Clarify what kind of meeting this is. Ask: “Is this an investigatory interview/fact-finding meeting, or a disciplinary meeting? Am I required to attend, and by when?”
If you’re union-represented, request representation (Weingarten). If you are covered by a union/collective bargaining agreement and you reasonably believe the interview could lead to discipline, request your union representative before questioning begins. (In many workplaces, representation is not provided unless you ask.)
If you’re not union-represented, ask what support is allowed. Some employers allow a support person, witness, or HR present—ask HR what your policy permits.
Keep your response factual and bounded. If you’re pressured to respond immediately, say: “I want to cooperate. I need to review the allegation and any relevant documents first, then I can respond carefully.”
Create a private timeline right away. Write down:
- what you’ve been told (who told you, date/time, exact words if possible)
- relevant events (dates, meetings, messages, who was present)
- what records exist (emails, chats, schedules, project docs)
Preserve your materials without taking confidential data. Keep relevant emails/messages/notes intact and in place. Do not forward or download restricted/confidential workplace information to personal accounts or devices. If you’re worried you could lose access, ask HR how evidence will be shared with you during the process.
Avoid retaliation risk (even accidental). Do not change the coworker’s workload, shifts, access, evaluations, or day-to-day treatment because of the complaint. Don’t rally coworkers against them. If HR issues a “no contact” instruction, follow it exactly.
Use one support channel. If your employer has an Employee Assistance Program (EAP), consider using it for immediate stress support. If the complaint could realistically threaten your job or alleges discrimination/harassment, consider consulting an employment attorney privately once you have the written allegation and process details.

What can wait

You do not need to write a long statement or assemble “character references” before you know the specific allegations and timeline.
You do not need to decide today whether to resign, transfer, or counter-complain—those are high-stakes moves best made after you have the facts and the written process.
You do not need to “fix” workplace relationships right now; focus on staying professional and letting the formal process run.

Important reassurance

A formal complaint can feel like a punch to the stomach, but it does not automatically mean you will be disciplined. Most employers have a process to gather facts from multiple people before making decisions. Your safest first moves are calm, documented, and non-contact with the complainant.

Scope note

This is first-step guidance for the initial panic period. What happens next depends on your employer’s policy, whether you’re unionized, and what the complaint alleges.

Important note

This is general information, not legal advice. Workplace rights and employer obligations vary by state, industry, and whether you’re covered by a union contract. If you feel unsafe or in crisis, seek urgent help.
