Celebrate work anniversaries with these 30 thoughtful message examples to make every milestone feel meaningful, personal and worth remembering.

Whether it’s their very first year or their fifteenth, a work anniversary is worth celebrating. It’s a chance to pause and recognize the time, effort and heart someone has invested in your organization. Each year represents a journey of growth, dedication and impact.

Taking a moment to recognize that can go a long way. A thoughtful message can make employees feel appreciated, seen and proud of what they’ve accomplished.

In this blog, we’ll explore why celebrating work anniversaries are important and share 30 thoughtful (and ready-to-copy) work anniversary messages you can share with a colleague.

Why You Should Celebrate an Employee’s Work Anniversary

Work anniversaries are one of the most important — and often most overlooked — milestones in the employee experience. In the rush of day-to-day responsibilities, it’s easy for them to slip by without acknowledgement. But taking just a moment to celebrate them can have a meaningful and lasting impact.

Here’s why it matters:

It boosts morale: Recognizing an anniversary reminds employees their time and contributions are valued.
It reinforces belonging: Acknowledgement helps people feel more connected to their team and the organization.
It fuels retention: Employees who feel appreciated are more likely to stay — and stay engaged.
It builds a culture of appreciation: Recognizing milestones sets the tone for a positive, people-first workplace.
It motivates: Employees who feel their contributions are seen and valued are more likely to go the extra mile for their role and teammates.

In fact, employee recognition is one of the top drivers of employee engagement and retention. Research from Deloitte indicates that employee recognition can increase employee engagement, productivity and performance by 14%. On the other hand, Gallup notes that employees who don't feel recognized are twice as likely to say they'll quit in the next year.

So, when it comes to celebrating yearly work anniversaries, it's important to treat them as meaningful moments and not just another date on the calendar. A thoughtful message or a sincere gesture can remind employees that their presence matters — and that their contributions are making a difference.

How to Congratulate Employees for Years of Service

“I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.” ― Maya Angelou

Maya Angelou’s words are a powerful reminder, especially when it comes to moments like work anniversaries. Employee milestones come and go, but what really sticks is how you make someone feel in that moment. A thoughtful message can turn a simple “congrats” into a meaningful and memorable moment.

Here are a few simple ways to make your work anniversary messages feel more personal and impactful:

#1 Make It Personal and Specific

A generic “thanks for all you do” won’t leave a lasting impression. Instead, mention a project they led, a strength they bring to the team or a standout moment from the past year. When you highlight something personal and genuine, it shows that you’ve noticed their impact — and that kind of recognition really sticks.

Whether it’s a handwritten note, a thoughtful eCard or a shout-out in front of the team, taking the time to tailor your message to the recipient shows you truly see and appreciate the person behind the work.

#2 Match the Tone of the Employee Milestone

Not every anniversary deserves the same message. A one-year celebration is a great time to cheer someone on and celebrate their growth, while a ten- or twenty-year anniversary is the perfect time to reflect on their journey and express deeper gratitude for everything they’ve contributed.

#3 Celebrate Publicly and Privately

A personal thank-you can be powerful on its own, but pairing it with a public spotlight — like a shout-out in a team meeting or a message on a peer-to-peer recognition platform — amplifies the appreciation. Just remember, some people may prefer more private recognition, so always consider the employee’s comfort and personality when choosing how to celebrate.

#4 Pair it with a Reward

A heartfelt message goes a long way, but adding a meaningful reward can make their milestone(s) one they’ll truly remember. Whether it’s a personalized gift or the chance to choose something they’ll truly enjoy, a tangible reward reinforces your appreciation in a way that sticks long after the anniversary passes.
