What do you write in a birthday card for a coworker?
Open with their name, add one specific thing you appreciate about working with them, then close with a warm wish for the year ahead. Avoid age jokes unless you know they'd enjoy them. A coworker birthday card should feel personal without getting private: notice something real, keep it brief, and sign it.
A birthday card that circulates the whole team beats a rushed group email. Everyone adds their own line, and the person opens one card with all of it inside.

Frequently asked questions
One or two sentences is plenty when a group is signing. The card gets its warmth from lots of short personal notes rather than one long one. If you know the person well, three or four sentences is still comfortable to read.
