Work Anniversary Wishes & Messages
40 happy work anniversary messages for a coworker, employee or boss — for 1, 5, 10 and 20 years — professional, funny and short for LinkedIn, Slack or a card.
A work anniversary is one of the easiest moments to make someone feel valued — and one of the most often forgotten. A single sincere line from a manager or teammate goes a long way.
The best work anniversary messages name something specific the person has contributed. “Happy work anniversary” is fine; “Happy 5 years — this team would not have survived the migration without you” is the one they screenshot.
Below are 40 messages for coworkers, employees and bosses, organized by milestone. Use them on LinkedIn, in Slack, in an email or in a card.

- 4A wish for the year ahead.
One thing to skip: Avoid jokes that hint someone is “still here” or “stuck” — they can read as sarcasm. Keep it celebratory.
The difference one specific line makes
Same sentiment, two ways of saying it in a work anniversary message.
Most people write
“Happy work anniversary!”
Write this instead
“Happy 3-year work anniversary, Priya! Your onboarding guide is the reason every new hire gets up to speed so fast. Thank you for everything you do.”
Why it works: Naming a real contribution turns a routine notification into genuine recognition.
Three ways to open a work anniversary message
The first line is the hard part. Steal one of these and fill in the brackets.
“Happy work anniversary! Five years and you still make it look easy.”
“Congratulations on [number] years with [company]!”
“One year down — and what a year it has been.”
