Work anniversary letter for coworkers

Dear Sam,

Happy work anniversary. I know you do not love a fuss, so I will keep this between us, but I could not let today pass without telling you what working alongside you has meant to me.

When I started here, I was unsure of myself and convinced everyone else had it figured out. You were the one who told me that nobody really does, and then showed me how to act confident until it became true. You let me shadow your calls, you read my drafts, and you gave me your honest opinion even when it was not what I wanted to hear. A lot of the confidence I have at work today started with you.

What I admire most is how you treat people. You are just as patient with the newest intern as you are with our biggest client. You stay curious, you stay kind and you never let a bad day turn into a bad attitude. That is harder than it looks, and I have learned so much from watching you do it.

The letter

Dear {firstname},

Happy work anniversary. I know you do not love a fuss, so I will keep this between us, but I could not let today pass without telling you what working alongside you has meant to me.

When I started here, I was unsure of myself and convinced everyone else had it figured out. You were the one who told me that nobody really does, and then showed me how to act confident until it became true. You let me shadow your calls, you read my drafts, and you gave me your honest opinion even when it was not what I wanted to hear. A lot of the confidence I have at work today started with you.

What I admire most is how you treat people. You are just as patient with the newest intern as you are with our biggest client. You stay curious, you stay kind and you never let a bad day turn into a bad attitude. That is harder than it looks, and I have learned so much from watching you do it.

Thank you for another year of being my colleague, my mentor and my friend. I am proud to work with you.

With real appreciation,

Make it personal

  1. 1

    Pick the tone you share. Funny for the desk neighbor who loves a joke, heartfelt for the colleague who carried you through a hard month.

  2. 2

    Name one real moment. The launch, the late night, the coffee run. One concrete detail turns a generic line into a thank-you.

  3. 3

    Choose the place. A team thread for a cheerful shoutout, a direct message or a card for something personal.
