A colleague who will not stop: the paper trail, step by step

The record most people keep of a colleague who will not stop is the wrong one. It is long, written weeks later in one sitting, explains how the behavior felt, and argues a case. Whoever can act on it cannot use it, because none of it can be checked.

The record that works is dull. Short entries, one per event, written the same day, in the language of what happened rather than what it meant. Its job is not to prove you right, but to give a decision-maker a timeline they can verify.

What a usable entry looks like

Six fields, no paragraphs, under a minute.

• Date and time. Precise. "Tuesday the 3rd, about 2:15pm."
• Where. The room, the shift, the call, the channel.
• Who was present. Names, including anyone in earshot who did not take part.
• What was said or done. Quoted where you can. The action, not the intent.
• What you did, including if the answer is nothing.
• What exists elsewhere. A thread, a schedule, a badge log, a ticket.

Write "he said 'you're wasting everyone's time' at the Thursday standup" rather than "he humiliated me again." The first is checkable. The second is an interpretation, and interpretations get argued about instead of the conduct.

The same entry on a floor or a ward: "Sat 14th, 6:40am, bay 3, [coworker] and the shift lead present. [Name] said 'don't bother, you'll only do it wrong' when I picked up the pallet jack." Thirty seconds, before you clock out.

Day zero: the ask, said plainly

Before there is a trail, there is one clear request, made once, in words nobody can claim to have missed.

"I need you to stop commenting on my work in front of the team. If you have a problem with something I have done, bring it to me directly."

Normal voice, not a question. Then log it as the first entry: date, time, what you said, who heard it.

If speaking to the person directly is not safe, skip it and go straight to the formal message. Nothing here requires you to confront anyone.

The first two weeks

You are looking for pattern, not one provable event. Pattern turns "a personality clash" into something an employer has to handle as a process.

• Same day, every time. An entry written the next morning is worth less. One written two weeks later is a memory, and memories get challenged.
• Log the ordinary ones. The small repeated things carry the pattern. The dramatic one alone reads as isolated.
• Log your own conduct too. A record that shows you at fault twice is more credible than one where you never are.
• Save the artifacts as you go. Screenshot the thread, keep the schedule.

Keep it somewhere that is not your work account and not a company device, and take nothing containing customer, personnel or confidential material.

The message that makes it formal

At some point this stops being a difficulty between two people and becomes something the employer is on notice about. That moment is made by a message, not a feeling. Send it to your manager, or to HR if your manager is the subject, with a subject line still searchable in a year.

Subject: Formal concern - conduct of [name], ongoing since 3 June

"I am raising this formally so it is on record.

Since 3 June, [name] has repeatedly criticized my work in front of colleagues and twice reassigned my tasks without telling me. I have a dated log of eleven incidents between 3 June and 14 July, with names of those present, available on request.

On 11 June I asked him directly to stop. The conduct continued after that date.

I would like to know what the process is, who will be looking at it, and the timescale. I would like the response in writing."

Three things make it formal: the word "formally," a date range, and a request for a process and a timescale. Do not attach the log. Offer it and send it when asked, so you know who holds a copy.

With no work email, the same message goes on paper. Write it out, hand it to the supervisor or the office, and photograph what you handed over. If there is a complaint form, use it, and photograph that too.

The date that matters later is not the date it started. It is the date you can prove somebody with authority was told.

Who to take it to

Your manager first, unless they are the subject or have been told and nothing changed. Then HR. If you are represented, your steward before HR, because they know how the process runs.

Outside the employer the door depends on the conduct. Discrimination and harassment go to the state or federal agency that takes those complaints. Safety goes to the workplace safety agency covering your state. If raising it has already cost you hours or shifts, pay for an hour of an attorney's time.

What this article is not doing

We are not telling you whether what is happening is unlawful. That depends on the conduct, the characteristics involved, the employer's size, the state, and facts no article has. Do not decide it yourself either way.

Keep the dated record, send the formal message, take both to someone qualified. The record is what makes that conversation worth having.
