Work Anniversary Wishes for a Former Boss
Send a former boss a short work anniversary note that names one specific thing they taught you or did for your career. Say where it shows up in your work today. Wish them well at [Company]. The rule: thank them for a real moment, not the anniversary itself. That makes the message feel personal and keeps the door open.
A former boss is one of the most valuable people in your network. They can vouch for your work, refer you and open doors years later. A work anniversary is a natural, low-pressure reason to show you remember what they did for you.
What lands is a specific memory. Name the project, the feedback or the risk they took on you. Say how it still shapes your work. Keep it short, make it about them, and leave out any ask.

1. Email: thank them for one specific lesson
Subject: Happy work anniversary, [Name]
Why it works: One real lesson they gave you, still in use, is the most meaningful thing a former report can say.
2. Text: short and warm, for a boss you still text
Why it works: It is short enough for a text and still carries a specific memory.
3. Email: milestone year, like ten years
Subject: Ten years at [Company]
Why it works: Noting what they built over the years honors the milestone, not just the number.
4. Email: after years of silence, no ask
Subject: Congratulations on [number] years
Why it works: A brief update tied to their influence reconnects without pressure. Saying "no need to reply" makes it easy to receive.
5. LinkedIn message or text: they took a chance on you
Why it works: Few people thank a boss out loud for the risk they took. That is why it stays with them.
6. Email: first anniversary in their new role
Subject: One year at [Company]
Why it works: Linking their new success to what you saw them do before is a compliment. It also recalls your shared history.
7. Email: anniversary note that also thanks the old team
Subject: Happy anniversary to you (and the team)
Why it works: Including former colleagues shows warmth for the whole group. It doesn't water down the thanks to your boss.
8. Email: hard boss, honest respect
Subject: Congratulations on [number] years
Why it works: A candid, respectful note about a demanding boss is more believable than generic praise.
9. Text: instead of "happy work anniversary"
Why it works: It skips the stock phrase and still lands as a celebration with a personal thank you.
10. Email: you now work in a related field and could help them
Subject: Happy work anniversary from [Your Company]
Why it works: Offering help instead of asking for it flips the old roles in a way former bosses appreciate.

When to send it
- Send it on the day of the anniversary or the next morning. A week late reads as an afterthought.
- Use email or a LinkedIn message if you haven't spoken in over a year. Text only if you texted while working together.
- Give priority to milestone years like five, ten or fifteen. Add a line about what that long stretch means.
- If they recently had a hard stretch, like a reorganization, keep the note light. Skip any talk of the company's direction.
- Wait at least a few weeks after any ask you made of them. Then the anniversary note won't look like a setup.
Subject lines
- Happy work anniversary, [Name]
- Congratulations on [number] years
- [Number] years at [Company]
- Ten years at [Company]
- One year at [Company]
- Still using what you taught me
- A thank you, [number] years in
- Happy anniversary to you (and the team)
- Thinking of [specific project] today
- Congrats from a former team member
- Quick note on your anniversary
- You hired me, I never forgot
What to avoid
- Do not make the note about your own career news. One line of update is the most to include.
- Do not tuck a favor or reference request into an anniversary message.
- Do not use a generic quote or a stock phrase without anything personal around it.
- Do not mention why you left or anything negative about the company.
- Do not send a text if your only contact with them has been through work email.
After you send it
If they reply, answer within a day and keep it short. If they suggest catching up, offer two specific times. If you hear nothing, do not follow up. An anniversary note does not need a reply. Put the next touch on your calendar, roughly every three to four months. Try their birthday, a promotion or a useful article on something they care about. A former boss should hear from you a few times a year, always with something about them.

A study of 20 million LinkedIn members found that acquaintances, more than close friends, led to new jobs (Science, 2022). Capstone keeps those people warm. You approve every message, and it goes from your own email or phone.
Frequently asked questions
How to congratulate a boss on his work anniversary?
Send a short note that names the number of years and thanks him for one specific thing. That could be something he did for you or the team. Wish him a strong year ahead. Keep it about him and skip any request. Send it on the day or the next morning.
What is the best message for a work anniversary?
The best work anniversary message names one specific thing the person did and how it still matters to you. A real memory beats any polished quote, because it shows you were paying attention. For example: "Congratulations on five years. I still use the review checklist you built every week."
What to say instead of happy work anniversary?
Try "Congratulations on [number] years at [Company]" as an opener. "They're lucky to have had you for [number] years" works too, and so does "Here's to year [number]" as a start. Then add a specific thank you. Changing the opening matters less than adding one personal detail. That detail makes the message feel written for them.
Is it appropriate to send work anniversary wishes to a former boss?
Yes. It is a thoughtful, low-pressure way to stay in touch. Most former managers are glad to hear from people they led. Keep it short, make it specific to them, and don't pair it with a request. It works best when you have stayed in touch at least now and then.
Should I send work anniversary wishes by text, email or LinkedIn?
Use the channel you used most when you worked together. Text is fine if you texted then. Otherwise, email feels more thoughtful. LinkedIn messages work well when the anniversary alert is how you found out. Don't just react to the alert. A short written note is what they will remember.
