How to Say Goodbye to Coworkers You Didn't Like at Work

Here's the short answer. When you have to say goodbye to a coworker you didn't get along with, send a short private message before the group farewell email lands. Three sentences. Name one factual thing they helped you learn or ship, no revisionist warmth, no rehash of the friction, then a professional close. Send it once. Move on.

There is a specific awkwardness in the last week at a job. The group email is easy. The close teammates are easy. And then there is the person you butted heads with. The manager who never quite trusted you. The peer who competed on everything. The person who quietly made your Tuesdays worse.

You have three options. Say nothing. Send something fake and warm. Send something clean. Clean is what actually works.

What "clean" means

A clean farewell is honest, professional, and short. It does two useful things: it closes the loop for you, and it keeps the door open for a future you cannot predict — a reference check, a mutual friend, an industry that keeps folding back on itself. That is worth two minutes of your Wednesday morning.

A clean message has three parts:

• One factual sentence naming your last day and the shape of your exit.
• One specific sentence that names a real thing you learned from them or shipped with them. Not "great working with you." Something you can point to.
• One professional close — no promise you will not keep.

That is the whole message. It is not warm. It is not cold. It is calibrated to the actual relationship, which is why it lands.

Three templates you can adapt

The manager you struggled under.

"Hi [Name] — my last day is [date]. I wanted to say directly that the work on [specific project or initiative] taught me a lot about [specific skill or lesson]. I appreciate the time you took on that. All the best with the rest of the year."

The peer who never quite fit.

"Hi [Name] — leaving on [date]. Wanted to say that your [specific work: report, decision, launch, catch] on [thing] genuinely helped me. Wishing you well after I'm off the team."

The person you actively avoided.

"Hi [Name] — [date] is my last day. Wanted to close the loop directly. Thanks for the collaboration on [specific project]. All the best."

Notice what these do. They name one real thing. They do not perform warmth. They do not review the relationship. The third one is the shortest for a reason: sometimes there is only one factual thing to name, and it is fine to write that once and stop.

When to send it

Send these private notes the day before the group farewell email goes out. Not the same day. Not two hours before. A full day of separation lets the person receive the private note without wondering what the group email will say next. It also frees you from the "did they get my note" question during your last twenty-four hours.

Send from your work email while you still have it. Personal channels for people you did not get along with cross a line the relationship does not support. And keep it a message, not a calendar invite. A coffee proposal reads as either fake or ambiguous when the relationship was strained.

What to leave out

Six things do not belong anywhere in this message:

• The reason for the friction. Do not name it. Do not hint at it. Do not use "we had our moments" or any coded version. If they know, they know. If they don't, this is not the day to educate.
• Fake warmth. "You were such an inspiration" reads as sarcasm to the one person who knows you don't mean it — them.
• The next job. Never in this message. This is closure, not a pitch.
• An apology. Even if you owe one, this is not the delivery vehicle. A five-sentence exit note carries too much weight for a real apology and too little context to land one.
• A "keep in touch" line. You almost certainly will not, and both of you know that. Silence beats a promise you will not keep. That rule shows up all over our writing on who to actually thank before you leave — it applies even more here.
• The word "finally." "Finally moving on" and its cousins have a way of turning honest into bitter in one word.

If you find yourself writing a fourth sentence, you are usually about to break one of these rules. Delete it.

The harder question underneath this one

Once you have written the difficult-coworker notes, a quieter question tends to surface. Who else on the last twelve months of your calendar have you not written to yet? Memory over-weights the last two months and forgets everyone from last September. Not just the people you disliked — the senior PM you shipped one thing with, the cross-functional partner who moved teams six months ago, the recurring 1:1 with someone you actually liked and then lost touch with as work got heavy.

The list is worth writing once, honestly, off the source that actually knows the year: your work calendar.

It Was Great Working With You is a small tool that reads your calendar export and gives you a farewell list — including the quiet contributors your inbox and your memory have both dropped. Three minutes. It costs nothing to try.

Edge cases

The documented conflict. If HR was involved, or there was a formal complaint on either side, skip the personal note. Send nothing. The group email is enough, and it protects both of you from a message being read into. Reply politely and briefly if they reach out first.

The senior person you did not respect. An executive whose decisions you disagreed with. A skip level who never really saw you. Send the same three-sentence note. Name one specific thing, even if it is small — a memo they wrote, an all-hands moment, a call they made under real pressure. The senior version of a clean message reads the same as the peer version, because clean is clean.

They send you a warm goodbye first. Match the warmth by one small step, not by a full mile. If they wrote three warm paragraphs, write one warm one. That keeps you honest and keeps the exchange from escalating past the actual relationship. There is a longer breakdown of the reply cases in how to respond to farewell messages.

They ignore your note. Fine. That was always a possible outcome. You wrote it for closure, not for a reply.

The in-person moment, if it happens

If you run into them in the hallway or on a video call during the final week, a nod, a "take care," and a hand offered for a shake is the whole interaction. Do not stop to review. Do not linger. A short, warm-neutral moment is easier for both of you than a two-minute effort to force closure that neither of you needs.

If you are working remotely and there is no chance of running into them, the written message is the only exchange. That is fine. Not every relationship needs a face-to-face.

The one mistake that undoes all of this

The most common error is writing the note and then, at the last minute, adding a fourth sentence with subtext. "Wish we had worked together more" (you do not). "Hope you find what you're looking for" (this reads as pity or worse). "Sorry we never really connected" (this reopens a door you just closed).

Write three sentences. Reread them. Send them. Some of the specific patterns to avoid live in 6 farewell email mistakes to avoid.

A last thought

The instinct is to skip these people entirely, because writing a note to someone you did not like feels like doing them a favor they did not earn. It is not a favor. It is you closing a chapter cleanly so it does not follow you into the next one.

Once the difficult notes are handled, the rest of the goodbye list is easier. Pull the calendar and see who else the year quietly owes a note.
