Happy birthday to someone who makes work feel less like work. Here's to many more years of laughing at the same jokes.
How to write a birthday message for a colleague
- Keep it about them, not their age. Unless you know they'll laugh, avoid jokes about getting old.
- Mention something positive from work. "Thanks for all your help on the project" is personal without being too familiar.
- Match the card's tone. A shared card isn't the place for long messages — one or two lines is perfect.
- Sign with your full name. In big teams, people may not know who "J" is.
- Join in the celebration. A collection for a present or a cake in the kitchen says more than any message.
