How to write your own work anniversary message
- Name one real thing. A project, a habit, a moment. One specific line beats three generic ones.
- Match the milestone. A first year is about settling in; ten years is about impact. Say the number.
- Keep it short. Two or three sentences is plenty for a card, a Slack post or a LinkedIn comment.
- Say it in public, too. A shout-out in the team channel or meeting makes the message count twice.
How to reply to a work anniversary message
Keep it short and say thank you. On LinkedIn, one comment on your own post thanks everyone at once.
- Thank you so much! It's been a great year, and I'm lucky to work with people like you.
- Thanks, everyone! I appreciate the kind words. Here's to the next one.
- Thank you! Hard to believe it's been this long. I've learned so much from this team.
- Thank you! I really appreciate your support this year. It's made a big difference.
- Thank you all for the anniversary wishes! Grateful to work with such a great team.
- Thanks! I'd say it flew by, but I've been in a lot of meetings.
- Thank you for the recognition. I'm proud to be part of this team and look forward to the year ahead.
- Thank you! That means a lot.
Make the day more than a message
