Work anniversary messages: 60 examples for every milestone

A work anniversary gives everyone a reason to stop and say thank you. The message doesn’t have to be long. It has to sound like it was written for this person, not for anyone with a start date this month.

Below you’ll find 60 work anniversary messages: for a coworker, from a manager to an employee, for your boss, for each milestone from the first year to the twenty-fifth, short ones for a card or a Slack thread, and a few funny ones. First, a simple way to make any of them land.

How to write a work anniversary message

Most anniversary messages fall flat for the same reason: they celebrate the passing of time instead of the person. “Happy 3 years!” is friendly, but it would fit anyone. Add one sentence about what this person did, and the same note becomes recognition.

A simple formula works for almost every message:

1. Congratulate. “Happy work anniversary!” or “Congratulations on five years.”
2. Name something specific. A project, a habit, a moment: “the onboarding checklist you rebuilt,” “how you always pick up when a customer is stuck.”
3. Say what it changed. “New hires know what to do in their first week.” “Customers ask for you by name.”
4. Look ahead. “I’m glad we get to keep working together.” “Here’s to the next year.”

Put together: “Happy work anniversary, Priya! The onboarding checklist you rebuilt this spring means every new hire now knows what to do in their first week. I’m really glad you’re on this team. Here’s to year three.”

Send it on the day, or the last workday before if it falls on a weekend, and in the setting the person likes: a public channel suits most people, some would rather get a private note.

If you’re stuck for words, the free thank-you message generator has a work anniversary option: add their name, the years and what they did, and it suggests messages you can copy and edit.

Work anniversary messages by milestone

The milestone changes the tone. A first anniversary is a welcome that stuck; a tenth is a career. Long tenure is also rarer than it looks. The median wage and salary worker in the United States had been with their current employer for 4.1 years in January 2026, according to the Bureau of Labor Statistics, and the share who reach ten years depends heavily on age:

• 25 to 292.4%
• 30 to 348.8%
• 35 to 3920.3%
• 40 to 4430.1%
• 45 to 4938.1%
• 50 to 5445.2%
• 55 to 5949.9%
• 60 to 6452.6%
• 65 and over53.1%

Why work anniversaries are worth celebrating

An anniversary is a natural moment for recognition, and recognition goes with people who are engaged and stay. In Gallup and Workhuman’s 2022 survey of 7,636 U.S. employees, only about half (51%) planned to be at their current job five years from now. When an employer recognizes life events and work milestones, the report says, employees are 3 times as likely to strongly agree they feel connected to their culture and more than 30% more likely to say they plan to be at their organization in five years.

Drawing attention to these events serves a dual purpose: It celebrates employees’ achievements while sending important messages about the value placed on progress and continued commitment.

But an anniversary shouldn’t be the only time someone hears thank you all year. It works best on top of everyday recognition from colleagues. See how often to recognize employees, and how to build an employee recognition program that includes milestones.

How to celebrate a work anniversary as a team

A message from one person is nice. A message from the whole team is something people keep.

• Collect messages on a board. Start it a week ahead, invite the team to sign, and share it on the day.
• Say it in the team channel or the weekly meeting: the number of years and one thing they did this year.
• Tie it to a value. If your company has values, name the one this person lives.
• Mark the big ones a little bigger. Five, ten and twenty years might also come with lunch, a day off or a gift, next to the messages, not instead of them.

How Upreciated helps

Upreciated is employee recognition software for teams of about 10 to 500 people. Colleagues recognize each other on boards and from Slack or Microsoft Teams, tagged with company values, and analytics show HR who’s been missed. Work anniversary boards come with it: start dates come in from BambooHR or a spreadsheet, a board goes up a week ahead for colleagues to sign, and it stays a surprise until the morning of the day.

Frequently asked questions

What do you write in a work anniversary message?

Congratulate the person, name one specific thing they did this year, say what difference it made, and look ahead. For example: “Happy work anniversary! The onboarding guide you rebuilt has made every new hire’s first week easier. Here’s to year three.”

What is a good short work anniversary message?

“Happy work anniversary! So glad you’re here.” or “Congrats on another great year, thanks for all you do.” One warm line and the person’s name are enough; add a specific detail if you have room.

How do you say happy work anniversary professionally?

Keep it warm and specific: “Congratulations on your five-year anniversary with us. Thank you for your dedication and the care you bring to every project.” Leave out in-jokes and keep the focus on their work.

Should a manager acknowledge an employee’s work anniversary?

Yes. Only 23% of employees strongly agree their organization has a system in place to recognize work milestones, according to Gallup and Workhuman, so a manager who marks the day stands out. A specific message on the day is enough; for bigger milestones, ask the team to add theirs too.
