Work anniversary messages for a coworker, from year one to twenty

A good work anniversary message names the years and says one true thing about the person. Two or three sentences are plenty. The lines below are for a coworker who is staying, sorted first by how long they've been there and then by how well you know them.

An example: Felix started at the city greenhouse on a wet Monday in March, five years ago. Nadia had been growing flowers for the city's parks there for twelve years by then. On his first morning she showed him how to water seedlings without knocking them flat. This March, on his fifth work anniversary, Felix found a small wooden plant label pushed into the pot of rosemary on his bench. On the back, in Nadia's small pencil letters, it said: "Planted here five years ago. Grew faster than anything else in the greenhouse. Happy anniversary, Felix." He laughed and held it up. Nadia stood right next to him with a tray of pansies, acting as if she'd had nothing to do with it. The label is still in that pot.

Your coworker's first year

One year in, many people still remember their first week: the badge that didn't open the door, the names they kept mixing up. A first anniversary message can tell them you're glad they stayed.

• "One year already? It feels like you've been part of this team much longer."
• "Happy first work anniversary, Keiko. I'm glad you picked us."
• "A year ago you asked us where everything was. Now we all ask you."
• "Year one, done. I hope you like it here as much as we like having you."

Five years on the same team

Five years is long enough for shared stories. Borrow one of them, and the message will sound like it came from you.

• "Five years of sitting across from you, and you still make me laugh before nine."
• "Happy fifth work anniversary! You've seen this place through two office moves and one very long winter."
• "Five years ago you were the new one. Now you're the person the new ones look for."
• "Happy 5 years, Omar. Thanks for every time you said 'leave it with me' and then really did."

Ten years: a decade at the same place

Ten years in one place is a big number. Say it out loud, and tell them one thing the team would be missing without them.

• "Ten years! Most of what I know about this job, I picked up from watching you."
• "Happy 10th work anniversary. You're a big part of why this team feels like a team."
• "A decade here, and you still say good morning to every single person."
• "Ten years of your calm voice on the busiest days. Happy anniversary, Marta."

Twenty years and more

After twenty, twenty-five or thirty years, someone has known the place longer than most of the people in it. Write about who they are now and how glad you are to work beside them.

• "Happy 20th work anniversary. Half the people on this floor learned the job from you, me included."
• "Twenty-five years! You remember how it all started, and you still welcome every new idea."
• "Happy 25 years, Grace. Thank you for knowing everyone's name, and everyone's birthday."
• "Thirty years here, and still the first to laugh at a good joke. Happy anniversary."

Write it for how well you know them

How close you are changes the message as much as the number does.

If you barely know them, their name, the years and a kind wish are enough.

• "Happy work anniversary, Wes. Here's to a good year ahead."
• "I just saw it's six years for you today. Congratulations!"
• "Happy anniversary from the other end of the hallway."

If you work side by side, add one small thing from the days you share.

• "Eight years of sharing a window, and you still let me have the side with the view."
• "Happy anniversary to the one person who always knows which meeting room is free."
• "Four years of Monday check-ins, and yours is still the one I look forward to."

If they're a work friend, you can be as warm and silly as you'd be outside work.

• "Six years ago I started a job. A few months later I had a friend. Happy anniversary."
• "Same lunch table, six years running. Happy work anniversary to my favorite colleague."
• "Of everything this job has given me, you're what I'd keep."

A colleague usually turns into a friend in small steps, and work friends follows how that happens.

Short work anniversary messages for the team chat

Many teams post anniversaries in a group channel, and a short reply under the post is often all that's needed. For a remote coworker, the chat may be the only place you see each other, so a line of your own means more than a thumbs up.

• "Happy anniversary! Glad you're on this team."
• "Congrats on three years, Hana!"
• "Seven years! That deserves more than an emoji."
• "Happy anniversary from the other side of the screen. Our calls are better with you on them."

Work anniversary quotes and sayings for a group post

These general lines work at the top of a team post or in a card the whole group signs.

• "Good years at work are mostly made of good people."
• "Some colleagues make a place better just by turning up every morning."
• "The years go quickly when the person at the next desk is easy company."
• "Every team has someone everyone turns to. Today we celebrate ours."

Funny work anniversary messages

Tease the workplace, the calendar or yourself. Their age stays out of it.

• "Happy 10 years! You've officially been here longer than the carpet."
• "Five years, and you still haven't learned to say no to me. Happy anniversary."
• "Fifteen years! At this point the building should be named after you."
• "Happy work anniversary. You remember every password on this floor except your own."

If the team chat could use a laugh too, work jokes has a joke of the day for every workday.

From a manager to someone on the team

If you lead the team, a work anniversary is a chance to thank someone as a person. Keep it about them and the team, and leave plans and numbers for another day.

• "Happy five years, Nils. I'm glad you're on this team, and I hope you know it."
• "Thank you for ten years of making new people feel welcome."
• "Three years ago you joined a group of strangers. Now it's hard to picture the team without you."
• "Happy anniversary. The team is a kinder place with you in it."

If the anniversary comes with a promotion, congratulations messages has lines for that. A birthday has its own lines in birthday wishes for a coworker. And when a coworker is moving on, farewell messages for a coworker has words for their last day.

When the anniversary is yours

Someone posts your date in the team channel and the kind words start coming in. A short thank you is all it needs.

• "Thank you, everyone! Hard to believe it's been five years."
• "Thanks for the kind words. I couldn't ask for better people to spend my weekdays with."
• "Thank you! The years went fast, and that's because of all of you."

If someone wrote you a longer note, these thank you card lines include a few for coworkers.

Who wants the whole team to know, and who wants a quiet note

Some people love seeing their name in the team channel with twenty replies under it. Others would rather get one private message and no fuss at all. Type is part of that. Here is how six of the 16 types take a work anniversary:

• Analyst trusts one exact, honest line in a private message more than a long thread of exclamation marks.
• Inspector checks that the number of years is right, and a message sent on the actual day matters to them.
• Diplomat enjoys the public post and every reply in the busy thread under it.
• Entrepreneur likes a short, lively message and a plan to mark it with the team on Friday.
• Guardian values a sincere private word from the few people they're close to, and remembers who sent one.
• Encourager answers every reply and loves a line about how they bring people together.

Nadia is close to an Inspector. She put Felix's start date in her own calendar in his first week.

Why some coworkers feel like old friends by year five

Two people can share a bench or a desk for ten years and stay polite strangers. Another pair feels like old friends by the first summer. Typeza looks at the two types in a pair and names the relationship type between them, with what comes naturally and what takes some patience. To see yours with one colleague, the friendship compatibility test is free, and afterwards you can invite that colleague from your own result.
