75+ Work Anniversary Wishes for a Colleague (1 Year to 25 Years)

Work anniversaries are the most under-celebrated milestone at work. Birthdays happen to everyone; a work anniversary is something the person did — a year (or ten) of showing up, carrying the pager, training the new folks, surviving the reorgs. Which is why “congrats on 5 years!” feels thin. The messages below actually honor the time.

The one rule

Anchor the message in something that happened during the years, not the number itself. “Three years, and you’re still the person everyone asks first” beats “Happy 3rd workaversary!” every single time. The number is the occasion; the impact is the message.

One year

1. One year in and it already feels like you’ve always been here. Happy work anniversary!
2. Happy first workaversary! You went from “the new person” to “the person we ask” impressively fast.
3. A year of great work and better company. Glad you chose us, [Name]!
4. 365 days, countless saves. Happy anniversary — year two is going to be even better.
5. Happy 1 year! The bravest thing you did was accept the offer. The smartest thing we did was make it.
6. One lap around the sun with us — and you’ve made every sprint of it better. Congrats!
7. Happy first anniversary! Officially no longer allowed to blame things on being new.

Two to four years

8. Two years of you making this look easy. We see how not-easy it is. Happy anniversary!
9. Happy 3rd anniversary, [Name] — three years and you still answer questions faster than the wiki.
10. Three years, [X] projects, one irreplaceable teammate. Congratulations!
11. Happy workaversary! Year four and your standards haven’t dropped an inch. Ours rose to meet them.
12. Two years in, and “ask [Name]” has become an official troubleshooting step. Congrats!
13. Happy anniversary! Somehow you’ve been here [N] years and your enthusiasm still reads as week one.
14. Four years of steady hands and sharp calls. This place is better because you’re in it.

Five years (the big one)

15. FIVE years! Half a decade of you raising the average around here. Happy anniversary, [Name]!
16. Happy 5th! You’ve outlasted three logo changes and two “new processes.” You’re the constant. Congrats.
17. Five years of hard problems handled quietly and wins shared loudly. That’s rare. Congratulations!
18. Half a decade in, and new hires still get told “watch how [Name] does it.” Happy anniversary!
19. Happy 5 years! The company you joined and the company today are different in a hundred ways — many of them because of you.
20. Five years, and you still care like it’s your first quarter. That’s the whole secret, isn’t it? Congrats!

Ten years and beyond

21. TEN. YEARS. A decade of showing up, leveling up, and lifting everyone around you. Happy anniversary, [Name]!
22. Happy 10th! You’re not just part of the company’s history — you’re a load-bearing wall of it.
23. A decade of your judgment, your patience, and your Friday jokes. We’re the lucky ones. Congrats!
24. Ten years in, people don’t say “the company way” — they say “how [Name] does it.” Happy anniversary.
25. Happy 15th anniversary! You’ve mentored people who now mentor people. That’s a legacy, not a tenure.
26. Twenty years. Entire careers have started and flourished inside your one. Congratulations, [Name] — an honor to work with you.
27. Happy 25th! A quarter century of excellence. There should be a statue; instead there’s this card, signed by everyone who means it.

Why anniversaries slip through the cracks (and the fix)

Nobody forgets birthdays maliciously — but work anniversaries aren’t on anyone’s calendar, so they surface as a LinkedIn notification three days late. Two fixes:

• For a single milestone: set up a free group card the week before — everyone gets a personal email invite, and it delivers on the morning of the anniversary as an animated reveal. Free, unlimited signers.
• For every milestone, automatically: TeamRally tracks birthdays and work anniversaries for your whole org and opens the group card for the team ahead of time — nobody has to remember, sign-up invites just appear.
