Work Anniversary Messages for a UK Colleague — What to Write and When
Work anniversaries are consistently under-celebrated in British offices. Here is what to write — by year, by relationship, by how well you know them — and how to make it the kind of message they actually keep.
The work anniversary: why British offices are bad at it and how to fix that
British workplaces are considerably better at goodbye cards than milestone cards. We say goodbye properly and often forget to mark the anniversaries in between — which is a missed opportunity, because a work anniversary message from a manager or colleague at the one-year, five-year or ten-year mark is one of the most remembered things a person can receive at work. Here is what to write.
What makes a good work anniversary message
Three things: specificity (not "great contribution" but "the way you handled [specific thing]"), acknowledgement of the time that has passed (not just the outcome, but the consistency of showing up), and warmth that is proportional to how well you know them. A manager's message to a direct report should feel different from a peer's message to a close colleague.
From a manager to a direct report — 1 year
- One year in and you've already made a real mark. The quality of your work, your willingness to get stuck in and the way you've integrated with the team has been genuinely impressive. Here's to many more years — and to seeing where this goes.
- A first year well and truly earned. Thank you for everything you've brought to the team over the past twelve months. I'm looking forward to seeing what the next year holds.
From a peer to a colleague — 5 years
- Five years of showing up and being excellent at it. That kind of consistency is worth more than it often gets credit for. Happy work anniversary — I'm glad we've shared this many years of it.
- Half a decade. You've been here through more changes than I can count and navigated all of them with the same reliable competence. Happy anniversary. The team is better for having you in it.
Ten-year work anniversary messages
- Ten years is a proper achievement in any era, but particularly this one. Thank you for a decade of excellent work, accumulated knowledge and the kind of institutional memory that takes years to build and can't be replicated overnight. Happy anniversary.
- A decade at the same organisation is a choice made every day. Thank you for making it, and for everything you've contributed across those ten years. Happy work anniversary.
For someone who has been there longer than you have
- You were here before I arrived and I hope you'll be here long after. Thank you for the context, the patience with questions and the general steadiness that makes this team work. Happy anniversary.
- Happy work anniversary! You know things about this place that no document captures — and that knowledge is genuinely invaluable. Thank you for everything.
Short messages for the card
- Happy work anniversary! Here's to many more excellent years.
- Congratulations on your [X]-year milestone. Well and truly deserved.
- Happy anniversary — thank you for everything this year has held.
Make it a message worth keeping
A work anniversary card from the whole team — not just a Slack message from one person — tells someone their milestone was noticed collectively. An online work anniversary group card from Thankeeu lets everyone contribute messages, with an optional gift collection in GBP. Create one here.
