For a teammate
Recognize what they add to the team without turning the card into a review.
Happy birthday to the person who makes difficult work lighter. I hope the year gives some of that energy back to you.
Happy birthday! I hope you get to leave on time and do something you enjoy tonight.
Here’s to interesting ideas, generous people, and fewer meetings that should have been messages. Have a great birthday.
Thank you for noticing when someone needs context, credit, or a laugh. I hope you feel properly celebrated today.
Working with you proves that competence and kindness are not competing qualities. Wishing you a relaxed birthday.
